Why you should trust me

I've been reviewing phones and mobile accessories since 2011 and covering them for Wirecutter since 2015. This includes researching hundreds of cordless phones and testing dozens over the by v years. To improve sympathize the technology that makes these phones piece of work, I sought out experts including Ruth Wilson, marketing chair of the DECT Forum, the semiconductor group behind DECT engineering science, the wireless communication standard that all modernistic cordless phones use.

Retired audiologist Lisa Devlin tested the amplified phones in this guide. Devlin has non-syndromic, bilateral, built, mild-to-moderate sensorineural hearing loss. She uses two Oticon Opn S hearing aids and has prior experience with amplified phones. "In the by, I would rely on amplified phones with volume control," she told me, although she at present uses her iPhone and a Bluetooth connection to her hearing aids.

Who should get this

"Home phones" are nowhere near equally ubiquitous as they once were. A 2019 study from the Centers for Disease Control and Prevention (PDF) states that 61.3% of adults and 70.3% of children live in a home that doesn't take a landline but does have a wireless (cell) phone. That means tens of millions of American households yet have landlines, however.

Every bit a childless man who rarely makes phonation calls of whatever kind and lives in an apartment that has decent prison cell phone reception, I was surprised to detect but how many of my Wirecutter co-workers own and regularly use cordless phones. Some of my colleagues want a phone for emergencies: something that's always in the same place (every bit long equally the handset makes information technology back to the cradle), doesn't have to exist unlocked with a password, is simple enough for even a young child to utilize, and (if you have an quondam-school copper telephone line) tin can even work in a blackout. Other colleagues have poor cell reception in their homes and only need something that tin reliably make and receive calls. Finally, many cablevision companies offer a Voice over Internet Protocol (aka VoIP or "digital") phone service in discounted bundles with internet service or cable Telly, so having a telephone line can oft exist cheaper than non having one. If you lot have a line anyhow, why not get a phone to employ with it?

If y'all have hearing loss, an amplified phone's boosted voice levels and tone adjustments may arrive easier for yous to communicate. "Everybody'southward hearing loss is different," Lise Hamlin, director of communications for the Hearing Loss Association of America, told us. "And the key here is not so much the book as information technology is the quality of the sound." Some people benefit more than from louder calls, while others may need the loftier or low end of their caller'southward voice boosted, and nevertheless others require both.

How we picked

Because everyone now lives in a gilt age of smartphones, cordless phones don't get much attending anymore. When we published a previous version of this guide, in 2016, nosotros noted that there were relatively few independent, trustworthy reviews of cordless phones. Now, more than four years later, it'south nigh impossible to find upward-to-date thoughts from reputable sources. This fabricated information technology tricky for us to narrow our latest listing of test models, since the manufacturers that make cordless phones release dozens of similar models with only slightly different features.

So in an effort to zero in on the specific metrics and features we should expect for, we reached out to groups whose members would likely take an interest in these devices, and we searched for hobbyists and enthusiasts. Unfortunately, we striking a brick wall there, likewise: We simply couldn't find anyone with the expertise to speak near what makes a great cordless telephone. We were able to track downward people who could explain the applied science that makes these phones work, only when we contacted public interest groups, including AARP, that nosotros idea might accept insight into what people want in a cordless phone, they didn't have anything to share. The aforementioned was true when I put in a request with SciLine, a resource for journalists to connect with scientific sources. Heck, there'south not even a subreddit nearly the category.

Next, we turned to the phone makers themselves. Our research revealed that there are just two major manufacturers of cordless phones: Panasonic and VTech, the latter of which as well makes AT&T-branded phones. There are smaller brands, but for support and warranty purposes, we hewed closely to the larger brands.

We began our research by compiling a spreadsheet containing the specifications of the more than 100 phones we establish on these 3 brands' websites—a seemingly endless listing of confusing alphanumeric product names, only slightly differentiated characteristic sets, and designs with no meaningful differences among them. These companies seem to innovate and discontinue models at a whim; almost every phone we've recommended in a prior version of this guide has been discontinued within two years. Complicating things further, many models are bachelor only through sure retailers (Amazon, Target, Walmart, and and then on). Finding phones that fit our desired specifications and were actually available to buy was frustrating for us, and nosotros do this sort of thing for a living!

To figure out which features and specifications were the most important, we gathered a grouping of Wirecutter staffers who had cordless phones and asked why they used them and what features they found well-nigh useful. We combined that feedback with our inquiry to arrive at a list of criteria:

• Range: One of the biggest benefits of a cordless phone is that you can apply it far from its base, and the farther you tin go without your call breaking up, the better. You and your telephone should be able to roam effectually your house or apartment—and even your yard—without dropping the phone call. Panasonic's phones take a stated range of 1,300 feet, and VTech claims its top-of-the-line phones (including AT&T-branded models) have ranges of up to 2,300 feet. Of grade, these figures pertain to use in perfect conditions, and in the real globe, perfect conditions are rare: You're surrounded by walls, windows, other wireless devices, and power lines, all of which can touch how well a cordless telephone performs.
• Audio quality: A not bad cordless telephone offers well-baked, clear, loud audio for both you lot and the person you lot're calling. Information technology's commonly believed that home phones sound amend than cell phones. Whether that's true or non, you shouldn't have to struggle to make out what the person on the other finish is saying.
• Call-blocking features: With the increasing prevalence of robocalls, information technology's important that phones offer an constructive mode to cake them. On some phones, this is an active affair—you lot printing a button when a spam phone call comes in, and that number moves to a block list so it's blocked going forward. More-avant-garde phones offer pre-screening that prevents robocalls from getting to you in the start identify. In our enquiry, we gave bonus points for whatsoever feature that stopped the phone from ringing unless information technology was someone we wanted to hear from.
• Intuitive menu systems: On cordless phones, menus and navigation are universally bad compared with the touchscreen smartphone interfaces people are now accustomed to. You have to use fixed keys that aren't necessarily in an intuitive place, and you must use T9-style typing (imagine texting on a jail cell phone with a stock-still number pad) when you lot fill your address book with names. Though we call up all cordless phones take abrasive menus, some are less frustrating than others.
• DECT half-dozen.0: This is the wireless standard that allows a cordless handset to communicate with the base, and it's included in nearly any phone you can buy today. As Ruth Wilson, marketing chair of the DECT Forum, explained to us, this brusk-range communication engineering science is ideal for cordless phones considering information technology operates on a wavelength far away from those of Bluetooth, Wi-Fi, and other signals on the wireless spectrum that could potentially interfere.
• Full-duplex speakerphone: Full-duplex support (every bit opposed to one-half-duplex) is necessary if a speakerphone is present. "A device that is half-duplex can send or receive data, but not at the same time, such every bit a walkie-talkie," explains VoIP comparison site GetVoIP. With a total-duplex speakerphone, both parties can talk without having to worry about their conversation existence clipped.

Armed with the above criteria, we asked representatives from VTech and Panasonic which of their respective phones best fit the bill. Although nosotros normally wouldn't rely on what a manufacturer had to say about its own products, this was the only style for us to ensure that we weren't missing out on phones that might be sold only at sure retailers, or that we weren't including whatsoever that would soon be discontinued. After cross-referencing the suggestions against our own research, we called in 12 models:

• AT&T CL82219
• AT&T DL72210
• AT&T DLP73210
• AT&T EL52119
• Panasonic KX-TGC352B
• Panasonic KX-TGD510B
• Panasonic KX-TGE633M
• Panasonic KX-TGE675B
• VTech CS5229
• VTech CS6114
• VTech CS6124
• VTech IS8151-4

We used the same criteria to research amplified phones, with additional qualifications specific to their intended purpose.

• Hearing aid compatibility: The HLAA's Lise Hamlin told the states that the beginning thing someone shopping for an amplified telephone should expect for is hearing aid compatibility. "When somebody has a hearing assist, or a cochlear implant, or a bone ballast device," she said, "there could be some noise on the line." TIA-1083 (PDF) is a standard authored by the Telecommunications Industry Association that addresses cordless phone interference when a hearing assistance is used in the telecoil (T-coil) way. We included in our inquiry only those phones that have been certified compliant to the standard, which is fairly mutual merely not ubiquitous.
• Book and tone adjustment: Past definition, an amplified phone must raise the volume of the speaker on the other end of the line. There'southward currently no standard to tell whether a telephone is designed for mild, moderate, or astringent hearing loss, although such a standard has been thoroughly studied and proposed (PDF). There'southward also no minimum volume that'due south best for all people. Then although we didn't ready a threshold, nosotros considered just phones that specifically advertised boosted book. As for tone adjustment—the ability to alter the high and depression ends of the audio to account for different levels and kinds of hearing loss—we preferred phones that offered more levels of control because they're more probable to benefit more people. "The more control you have, the better," Hamlin told us. "You lot just want to be able to push the button until information technology sounds right."
• Headset or neck-loop jack, base/handset speakerphone, dull-spoken language mode, and visual ringing indicator: All of these features benefit the greater community of people with hearing loss, even if non every individual uses every 1 of them. A headset or cervix-loop jack allows telephone users to connect an assistive device that might be ameliorate for them than holding a telephone against their ear. Having speakerphone modes is of import considering information technology allows yet another way to listen; for some people, the concrete placement of the speaker might assistance them process the audio better. Slow-voice communication style does just what the name suggests, which can be helpful with fast speakers or detailed information. And a visual ringer means that fifty-fifty if y'all can't hear the telephone ring, you can encounter that it's ringing, and so y'all're less likely to miss a telephone call.

Afterwards our research, we chose to test the following three amplified models:

• Clarity XLC8
• Panasonic KX-TGM420W
• Panasonic KX-TGM450S

How nosotros tested

One time we had the phones in hand, we installed an Ooma Telo VoIP system—one of the more pop brands of boxes that plow your internet connection into a phone line—and began testing. Some aspects were obvious from the start, such as how similar the hardware was across many of the models; other features, including range and vocalization quality, required us to evaluate them more thoroughly.

To measure range, we prepare each phone's base station in the northwest corner on the 2d floor of a 2-story home. We then placed a call to the National Weather Service'southward automatic hotline, which provides a recorded message with the weather weather and forecast. We walked down the stairs, out of the house, and westward down the street, continuing to listen until the call started to break up. Even though the phones technically remained continued at that signal, they weren't pleasant to listen to. Thankfully, even the worst-performing phones made it several houses down the street (about 130 feet) before the indicate weakened.

Once we had identified models that performed well in the range test, we were left with 3 models that looked skilful in terms of range, specs, and features (compared with other phones in their cost brackets): the VTech CS6114 (a budget phone), the AT&T DL72210 (a midrange contender), and the VTech IS8151-4 (a potential upgrade pick). To evaluate vocalism quality on these iii models, we fabricated outgoing calls and left voicemails in which we read a brusque passage from Ralph Ellison's Invisible Man. As a control recording, we did the same with an iPhone XR using T-Mobile'south Wi-Fi calling to ensure there weren't whatsoever problems stemming from a weak cellular connection.

Nosotros then shared the voicemail recordings with 3 Wirecutter writers and editors and asked them to evaluate and rank the four clips (the test phones were not identified to the panel). It'due south possible that a traditional copper landline may have resulted in different functioning than we got with our VoIP setup, simply VoIP is a popular style to connect a phone, and it's rapidly replacing quondam-school copper. Spoiler warning: We found that (at least over VoIP) cordless phones don't necessarily audio any better than cell phones, specially when the cell phone is placing the call over Wi-Fi.

Having verified that all three phones had good-enough voice quality, we only navigated around each phone and played with its respective features to see how well they were implemented. Were the menus easy to navigate? (None of them were specially great, just some were worse.) How did the handsets and their buttons feel? How easy was it to read the screen? Several of the features were binary—they either existed or didn't, then nosotros naturally preferred the models where they were nowadays.

Retired audiologist Lisa Devlin performed similar tests with the amplified phones, allowing united states to evaluate range and outgoing audio quality. Additionally, she made calls using each phone and toggled through the diverse settings intended to aid hearing, including the volume-adjustment options, tone control, tiresome-speech and racket-reduction functions, and whatever audio assist or heave buttons.

Our pick: AT&T DL72210

Our pick

AT&T'due south DL72210 offers dandy range and clear audio, plus nearly all of the features almost people could promise for in a cordless telephone—all for a price lower than that of comparable handsets. This model has a long enough range that you'll be able to walk around your house without the connexion sputtering, and it's also the best-sounding telephone we tested—our panel ranked it even higher than an iPhone used with Wi-Fi calling. The package comes with two handsets, so you tin can have phones in different parts of your home. And this model includes features normally constitute merely on more than expensive phones, such as automatic phone call screening and a Bluetooth prison cell telephone connection.

Although the DL72210'due south range isn't the longest of the phones nosotros tested, information technology's plenty long enough for nearly whatever application. Nosotros were able to get virtually 260 feet away from the base of operations station before the sound on the other end of the call began to cut in and out. Some phones offered a range upwards of 450 feet in our tests, but 260 feet should still exist plenty for utilize in nearly people's homes. To put that number in perspective, we were able to go seven houses downwards the street with the DL72210 earlier our examination call began to break up. AT&T'south CL82219—a like phone in the same cost range but with fewer features—was able to get a business firm and a half further, which is bang-up, just that extra range is probably not necessary unless you accept an specially big property.

What the DL72210 lacks in extended range, it makes up for in telephone call quality. When reviewing sample recordings, our testers most universally preferred this phone's audio over the clips from the iPhone and the ii other cordless phones nosotros tested. "There'due south some racket, but your voice sounded warm," said one. And audio skillful Lauren Dragan, a Wirecutter senior staff writer, told us that the DL72210 really sounded clearer through her iPhone'southward earpiece than another iPhone did.

In addition to the DL72210's call quality, its package of features helps the phone stand out. Many phones at this price, including this one, offer details such as a button on the base station that pings the handset (then you lot can notice it), a digital answering arrangement (an answering machine without the tape), a full-duplex handset speakerphone, and one-touch call blocking (which lets you lot automatically add robocall numbers to your block list).

The DL72210's handset has a roomy screen, as cordless phones go, and large number keys. Photo: Michael Hession

But 2 features in particular assistance the DL72210 stand out compared with others in the same price range: smart call blocking and a Bluetooth cell telephone connexion. The onetime is a call-screening feature that nosotros've seen only on AT&T and VTech phones. It works by comparison the numbers from incoming callers against those in your phone volume, which you can add manually or from your prison cell telephone over Bluetooth. At that place are two unlike modes: "Screen robot" and "Screen unknown." In both cases, numbers in your contact list come through unimpeded, and numbers yous've already blocked don't come through at all. But callers without a caller ID, or those that are not already on ane of your approved/unapproved lists, are screened. In the "Screen robot" mode, all unknown callers must press the pound (#) key before your telephone will ring. If they don't, the phone call volition be rejected, and you'll never be bothered. In the "Screen unknown" profile, the caller is asked to say their name and and then press the pound key. If they exercise and so, their message is then played out loud, and you can choose to reply the call, answer and permit the number going forward, block the number, or send it to your answering organisation.

The DL72210'due south Bluetooth organisation allows yous to connect up to two devices to your dwelling phone: two jail cell phones, or a prison cell phone and a Bluetooth headset. When paired, your cordless telephone can then serve as an extension of your smartphone, allowing y'all to go out your mobile telephone by the base and and so wander around with the DL72210 handset. Information technology will also ring when your jail cell phone gets a phone call. This is handy for someone who might non have great cellular service throughout their entire home; you can position the base of operations where you exercise accept proficient service, leave your cell telephone next to information technology, and use the handset in areas where you don't.

In add-on, the Bluetooth connection allows you to trigger your smartphone's phonation assistant. That works fine, but it doesn't sound equally good equally talking to the banana directly through your cell phone; the interaction isn't as piece of cake equally but yelling out to a smart speaker that you may already have in your domicile, either. The Bluetooth function also lets you download your phone's contacts, although in our testing we ran into an issue where the telephone told us the directory was unavailable. That's not the primary reason you'd employ the Bluetooth connection, just we found the error annoying.

AT&T offers a i-year warranty on its phones, merely if you need to transport a telephone in for repairs, you lot have to package it yourself, send in a re-create of the sales receipt, and pay for postage. Although we generally advocate fixing your stuff rather than replacing it, there's a skillful gamble that if a cordless handset dies, ownership a new one will be cheaper than sending the busted unit back and forth.

Flaws but not dealbreakers

The DL72210's range was non every bit long as that of many other phones we tested; it began to break up at around 260 feet, compared with the 450 anxiety we got from the VTech IS8151-iv (our upgrade option) and the 445 feet we got from the highest-performing similarly priced phone, the AT&T CL82219. If you lot know yous demand extra range and are willing to surrender the Bluetooth connection, consider going with the CL82219.

If y'all've been exclusively using a smartphone for a while, going back to a cordless telephone's clunky user interface will be an adjustment. Video: Michael Hession

The phone's hardware and software are relatively refined compared with those of other cordless phones, although side by side to a touchscreen smartphone, they feel dated and clunky. The two-inch screen (measured diagonally) is monochrome, and the white backlighting glows for only a few seconds after you stop pressing buttons. The labyrinthine menu system made united states of america long for the swiping and tapping of our smartphones. Withal, we appreciated that the number keys glowed a soft blue, making them easy to see in the nighttime.

A great amplified phone: Panasonic KX-TGM420W

Photograph: Michael Hession

As well corking

For those with mild to moderate hearing loss looking for an amplified telephone, we recommend starting with Panasonic'due south KX-TGM420W. Information technology has all the features a dandy telephone should have, amplified or not, and when retired audiologist Lisa Devlin tested our amplified finalists, it was her favorite—the one she would tell her clients to get. The volume adjustments should be suitable for many people who need additional vocalization levels, and the 6 levels of tone aligning plus custom tones provide a greater range of vocalisation qualities than you can find on phones from any other company. The phone meets the TIA-1083 standard, so it offers compatibility with hearing aids without causing interference, and it works with headsets and cervix loops. And like all of our picks, the KX-TGM420W has good range and outgoing phonation quality.

Panasonic says that the KX-TGM420W can reach up to 40 dB and that the ringer can become up to 100 dB. (If that's still besides quiet, the KX-TGM450S variant gets upwards to l dB and 112 dB, respectively.) We didn't measure out the volume to confirm those numbers, but Devlin found that with her level of hearing loss, she didn't need to turn the phone upward all the way to reach a useful, comfortable listening level. "That would disqualify whatsoever product for me, if I e'er had to go to the maximum volume," she said.

Devlin too establish the tone adjustment to be satisfactory. A button on the side of the handset, higher up the volume rocker, allows you to cycle through six preset tones with different adjustments to the loftier-end, midrange, and low-terminate qualities of the vocalization on the other end. "For case, if I was talking to somebody and I hit the push, I could become from a more than low-pitch accent to another with a mid-pitch accent," she said. "And there were a couple that I could make very sharp, very high-pitched." Depending on a number of factors, including your particular type of hearing loss and the speaker's vocalisation, you may need to accommodate the tone even in the eye of a telephone call, and Devlin said it was simple to do and so. Panasonic besides offers custom tone settings, if yous're willing to fiddle around with the phone's menu, but our tester was happy with the presets.

The KX-TGM420W looks like most cordless phones simply has notable additions including a visual ringer and boost and ho-hum buttons. Photo: Michael Hession

The handset's tone and book buttons are easy to printing while yous're on a telephone call if you lot need to adjust them. Photo: Michael Hession

The KX-TGM420W is compliant with the TIA-1083 standard, and Devlin didn't observe any interference with her hearing aids. If you utilize a headset or induction neck loop, you can plug it into the jack on the side of the handset. Flashing lights on both the base station and the phone itself indicate when you're getting a telephone call, and the included slow-speech function is especially useful for reviewing voicemail messages. The KX-TGM420W also offers the standard features nosotros look for in any cordless phone, including a base speakerphone and handset speakerphone, call blocking, and a push on the base station to assist you lot observe the handset.

There are a few features that Devlin found didn't piece of work every bit advertised, but none of the issues stood out every bit a dealbreaker. Although Panasonic advertises a groundwork-noise reduction characteristic on this amplified telephone, Devlin wasn't able to activate it while on a call. She said it was bad-mannered to navigate to the feature on the KX-TGM420W, and that it didn't make a noticeable difference in the quality of the telephone call. In the terminate, she found it was more constructive to only ask the person she was conversing with to step out of the noisy environment. The "boost" button was also something of a bust, but that was true for all three phones we tested. "Information technology successfully achieved a loudness boost," Devlin said, "but it altered the tone and was awkward to readjust while on a telephone call." Instead, she recommends manually adjusting the volume and tone to suit your needs.

Budget pick: VTech CS6114

Budget selection

VTech CS6114

A basic cordless phone

This model is corking if you demand only a clear-sounding phone without whatever bells or whistles. It'southward an ideal candidate to keep around in case of an emergency.

Buying Options

If you lot merely want to have a phone effectually for emergencies, or if yous don't care most anything other than existence able to pick upwardly and dial, nosotros recommend the VTech CS6114. It's as uncomplicated as can be, but it has a long range, totally passable vocalisation quality, and an exceptionally depression cost—roughly the same as that of an iPhone charging cable. Even though you're giving upward plenty of features compared with choosing our meridian pick, yous're paying next to nothing for the peace of listen a home phone can bring.

We were impressed with the CS6114's range, which extended farther than that of some much more expensive models. The incoming voice on our call didn't start to break up until about 310 feet abroad—just over a football field's length. Even before it bankrupt up, the voice quality wasn't particularly stiff compared with what you become from higher-end phones, but that shouldn't come equally a huge surprise. "This sounds pinched, but yous get the consonants better" than with the VTech IS8151-four or an iPhone XR on Wi-Fi calling, said Wirecutter senior staff writer Lauren Dragan. "It is a narrow, reedy sound, but it's easy to understand the words." In evaluating the four phone letters she listened to, Lauren nonetheless ranked this phone's voice quality the lowest. But once again, it's non shocking that a $15 telephone performed worse than handsets that toll several times more than.

The VTech CS6114 offers the basics—dial, caller ID, phone book—and little else. Photo: Michael Hession

The only other features the CS6114 offers are a thirty-number phone book, caller ID, and a button on the base station to locate the handset if yous've misplaced information technology. Otherwise, information technology lacks any sort of call blocking, speakerphone, or digital answering organisation, and it has no ability to connect to your cell phone. The hardware itself is light and plasticky, and the screen is small. But nosotros like that the entirety of each number key glows, rather than simply the perimeter. The base is compatible with wall mounts, but it doesn't come up with ane.

Fifty-fifty though VTech makes phones nether both its own make and AT&T, its i-yr warranty process is singled-out from AT&T's. The CS6114 uses the same affordable 300 mAh battery as the DL72210 does.

Upgrade option: VTech IS8151-iv

Photo: Michael Hession

Upgrade pick

The VTech IS8151-four offers impressive range, good-enough vocalisation quality, four handsets, and every other feature we can think of. A speakerphone and dial pad on the base station? Bank check. Smart call blocking? Yep. Cellular connection? Yeah, indeed. If you want everything a cordless phone has to offering, the IS8151-4 is the model you're looking for. And even though information technology's more expensive than our other picks, the cost per handset is actually less than that of the AT&T DL72210.

In our standardized distance examination, the IS8151-iv traveled further—an impressive 450 anxiety, or the length of almost 13 school buses—than any other phone before our call bankrupt up. VTech markets the phone equally supporting "super long range," which it defines every bit ii,300 feet, but it's not surprising that the telephone fell far brusque of that effigy in real-world conditions; all the phones we tested delivered far less than their stated ranges.

Our testers' opinions on the IS8151-4's voice quality varied—individual respondents placed it 2d, third, and fourth in their evaluations. One described the voice quality equally being a little deadened but perfectly understandable. Again, your results may vary depending on whether yous're using a traditional copper wire or a VoIP connection (and, in the latter case, on how much bandwidth is available).

The IS8151-4 is slightly more than modern-looking than our other picks, simply it still has a vintage experience compared with a touchscreen phone. Photograph: Michael Hession

The IS8151-4 has a panoply of features; there's really nix another phone does that it doesn't do. In terms of hardware, it has a punch pad and a speakerphone on the base unit, something that less-expensive phones only don't offer. This model comes with a mounting bracket, too. Equally for robocall blocking, the IS8151-four is equipped with both one-touch blocking and (like the AT&T DL72210) smart call blocking and Bluetooth cell phone connexion features.

If you don't need four handsets, VTech sells an otherwise-identical iii-handset package, but since it'due south just well-nigh $10 less, it's not as expert a value. If y'all need more handsets, you'll besides find a five-handset option. Y'all tin can extend the phone to include upwardly to 12 handsets, but as of this writing the IS8101 accessory handset is out of stock at Amazon and not readily available anywhere else.

Other adept cordless phones

Not-amplified

VTech'due south CS6124 is identical to the CS6114, except that the CS6124 has a digital answering system on its base. Most people don't need this characteristic on a budget phone, just if you do, the CS6124 is a adept choice.

AT&T's CL82219 is similar to the AT&T DL72210, with about of the same features, an almost-identical handset, and a comparable price. The big difference is that the CL82219 doesn't have a Bluetooth connectedness, so you lot can't pair it with your cell phone. In testing, we were able to take the CL82219 about a house and a one-half further before the incoming audio broke up, but that extra range isn't enough of a bonus to be worth giving up jail cell telephone pairing.

Amplified

Panasonic'southward KX-TGM450S is a noticeably louder variant of our amplified pick, which may make it better suited to people with more astringent hearing loss. Panasonic says the KX-TGM450S's vocalisation volume can reach l dB and the ringer can go up to 112 dB, compared with 40 dB and 100 dB, respectively, for the KX-TGM420W. Retired audiologist Lisa Devlin slightly preferred the tone aligning on the KX-TGM450S, saying information technology was "slightly clearer when I went to a more high-pitched emphasis." She too noted that the slow-speech role, while identical between the two phones for recorded letters, worked better on the KX-TGM450S for alive calls because it slowed the speaker down more on the KX-TGM420W. These upgrades all come at a price: The KX-TGM450S is virtually twice as expensive every bit the KX-TGM420W. But if any of these features will help y'all communicate, that's a price well worth paying.

Panasonic'south KX-TGM430B is another variant of our amplified selection that offers the same features and volume, plus a Bluetooth connexion to your cell phone. Notwithstanding, it costs much more than, and then we recommend it only if a cell phone connectedness is especially important to yous.

The competition

Non-amplified

Panasonic'southward KX-TGD510B offers call blocking and a handset speakerphone, which VTech'south budget phones don't. But it costs twice as much every bit our upkeep option (the CS6114). If y'all're searching for a low-stop phone with some more than-advanced features, choose this 1.

VTech's CS5229 and AT&T'southward EL52119 both come with just one handset. Also, they don't have smart telephone call blocking or one-button telephone call blocking, and they don't connect to cell phones.

Because Panasonic's KX-TGE633M comes with a 3rd handset, it'south more than expensive than the AT&T DL72210. It doesn't support smart call blocking or connect to your cell phone, though.

Panasonic's KX-TGC352B is inexpensive compared with other two-handset bundles. But it doesn't have smart telephone call blocking, a digital answering organisation, or a Bluetooth cell phone connection.

Although AT&T'southward DLP73210 has features that match those of other loftier-end phones, it comes with only two handsets, and in our tests it had the shortest range of any telephone we tested, at virtually 130 feet.

Panasonic's KX-TGE675B doesn't offer smart call blocking, something nosotros consider a necessary characteristic for phones in its price range.

Amplified

At most $200, Clarity's XLC8 is the near expensive amplified phone we tested. It doesn't excel in any of the features it shares with the Panasonic KX-TGM420W, and information technology doesn't offering any boosted functionality. Our tester too constitute its tone adjustment to be neither easy to use nor effective.
