Quick Take
Sennheiser All-Day Clear is currently our top-rated OTC hearing aid, with an overall HearingTracker Score of 4.6 out of 5. In my hands-on testing, I found it comfortable enough for all-day wear, with reliable Bluetooth, easy handling, and good sound quality in everyday use.
The lab results were more mixed. HearAdvisor measured good overall performance, but results in background noise were weaker than those of many comparable prescription models. There are a few other compromises to keep in mind: user controls are limited, and the charger is relatively basic, though Sennheiser advertises up to 24 hours of battery life per charge.
The All-Day Clear costs $999.95 per pair before promotions. I’d shortlist it for comfort, connectivity, and strong overall performance, though for the price, you may also want consider entry-level prescription hearing aids.

What Is Sennheiser All-Day Clear?
If you’re an audiophile, audio engineer, or musician, you’re probably familiar with the Sennheiser brand, which has traditionally been known for its line of audio equipment. But when did they start making hearing aids?
Back in 2022, Sonova—the largest hearing aid manufacturer in the world, which also manufactures Phonak and Unitron hearing aids— acquired the Sennheiser consumer division. Think of it as a natural pairing between the worlds of hearing aids and consumer audio to develop better speech-enhancing earbuds and hearing aids.
The All-Day Clear is a Sonova-developed, Sonova-manufactured receiver-in-canal (RIC) hearing aid that places a small speaker in your ear that connects via a plastic-covered wire to an audio processing/amplifying device that sits behind your ear. Incidentally, this is the most popular style of hearing aids in the world, accounting for around 70% of the total market.

Where to Buy Sennheiser All-Day Clear
All-Day Clear can be purchased directly from the Sennheiser website or Big Box retailers, such as Best Buy, Amazon, Walmart, and Target. They are also available through Sonova’s AudioNova hearing clinic network, as well as the United Healthcare website for some of its members. Make sure to shop around, as prices between the websites can vary.
The prices and sellers discussed here are for the United States. If you’re shopping from the UK, Canada, or Australia, Sennheiser’s U.S. store terms exclude orders billed or shipped outside the United States. Check local availability, app access, and support with Sennheiser before importing a pair.
Who it's for
This is an OTC hearing aid, meaning it is intended for those with no worse than mild-to-moderate hearing loss. If you’re not sure what level of hearing loss you have, we strongly recommend visiting a hearing care professional for a comprehensive hearing exam and audiogram, or at least taking a good online hearing test to get an approximation of your hearing loss level. Sennheiser also offers its own 3-minute hearing screener.

Unboxing and Details on Sennheiser All-Day Clear
Having provided a quick overview of the tech, let’s now take a look at what comes in the box and then we’ll dive into what it’s like to use Sennheiser All-Day Clear.
Inside, you’ll find the charging case with your pair of All-Day Clear hearing aids already inside. They come preloaded with a medium vented dome, and you do get a few additional size options to suit your ears, balancing comfort with retention.
On the back of each device, there’s a rocker switch, and these hearing aids communicate wirelessly—so any adjustment you make on one aid applies to both (a nice feature not available in all OTC devices).
In the lower compartment of the box, you’ll find a User Manual and a QR code to download the All-Day Clear app. You’ll also get a micro-USB cable and wall adapter.
You’ll also find some maintenance tools, including wax guards. If you’ve never changed wax guards before, it can feel a little intimidating, but it’s actually pretty simple. Start by removing the dome. At the end of the receiver, you’ll see a small white filter: that’s the wax guard, and it’s there to keep debris from clogging the speaker. Use the tool to pull the old one out, flip it around, and press the new one in.
You won’t need to do this often, but if your hearing aids suddenly sound weak or stop working, this is one of the first things to check before assuming something is seriously wrong. You’ll also get a small cleaning tool and a few extra dome sizes to ensure a good fit and comfort.
The charging case for Sennheiser All-Day clear is solid, but it is not pocket-sized and feels a bit behind the times for a few key reasons. First, there’s no internal battery, so you can’t charge your hearing aids on the go; the case has to be plugged in to charge the devices. Sennheiser now sells an optional All-Day Clear Power Pack for $149.95 that attaches to the bottom of the charging case and provides 2-3 full charges for the hearing aids. But, frankly, this is something many OTC hearing aids incorporate into their charging case designs.
Second, it uses micro-USB. Sennheiser includes the cable, which is good; however, if you forget it while traveling, there’s a decent chance you won’t have a backup lying around. Lastly, placing the hearing aids into the charger takes a little more effort than it should. Instead of a nice magnetic lock, it feels very mechanical, and it can be more difficult to seat and remove the hearing aids—not a huge deal, but if dexterity or hand strength is a concern, it’s worth keeping in mind.
Sennheiser now lists battery life at up to 24 hours on a single charge, depending on usage, rather than the 20 hours cited in earlier materials. A full recharge can take up to 3 hours. As my colleague Matthew Allsop has demonstrated, battery status can be checked in the All-Day Clear app, and the hearing aids’ indicator lights show approximate charge while in the charger: blinking red for under 10%, orange for 11-80%, and green for 81-99%; the light turns solid green when fully charged.

Sennheiser All-Day Clear Wireless Features
Sennheiser All-Day Clear OTC hearing aids are self-fitting hearing aids, which we’ll come back to in just a moment, but the key takeaway is that you must use the All-Day Clear app for setup and programming.
And honestly, that’s a good thing. Once you connect the devices to your iOS or Android device, you unlock Bluetooth streaming and sound customization. Pairing was straightforward in my testing. The app is compatible with Bluetooth-enabled smartphones and tablets running at least iOS 14 or Android 8.0 (note that the app works on tablets but isn’t optimized for them).
After you pair the devices with your phone or tablet, you’ll go through something called “My Sound Profile.” This is Sennheiser’s onboarding process, where you’ll listen to a speech sample and make a few simple choices around volume and clarity. This customizes the sound using your speech preferences; it does not measure your hearing thresholds or let you enter an audiogram. I found the controls limited, so I’d use the trial period to check how well the available adjustments meet your listening needs.
Turning back to the app-based setup, once you’ve completed your sound profile, you’ll find standard controls like Volume and Program selection. There’s an additional “Fine Tune” section with a 3-band EQ for additional customization. You’ll also see a Wind Noise Reduction toggle; however, I’ll be honest: I didn’t notice much of a difference when using it. But to be fair, wind noise wasn’t a major issue during my testing anyway.
:format(webp))
Sound modes are listed at the top of the app’s sound control screen. You can also change the volume and, as noted, activate the Wind Noise Reduction program. However, as Matthew has pointed out, once the hearing aids are restarted, they will return to their default settings.
One small frustration with the app is its handling of connectivity. Every time I closed and reopened it, my hearing aids needed to reconnect. And even if I left the app open (e.g., for more than a minute or so), All-Day Clear would time out and disconnect on its own.
This is likely done to conserve battery life, but it does mean you’re waiting a second or two every time you want to make an adjustment. It’s not a deal-breaker, but, similar to the charger insertion and removal comment I made in the last section, it’s another point where I feel usability could be improved.
Sennheiser All-Day Clear is designed to be fully automatic, adjusting to different sound scenes as you encounter them. As noted earlier, in addition to the app, they also have onboard push-button controls for on/off, volume adjustment, sound mode selection, and phone call acceptance/rejection. Unlike some of Sonova’s advanced prescription hearing aids, this device has no tap controls.
How Sennheiser All-Day Clear Performed in the HearAdvisor Lab
All-Day Clear’s strongest lab results were speech clarity in quiet, music streaming, and control of feedback—the whistling hearing aids can sometimes produce. Speech in quiet and streaming quality were well above the OTC averages shown below, and feedback handling was excellent in both tested fits.
Noise was the weaker point. Speech-in-noise scores were only slightly above the OTC average, so busy restaurants and group conversations deserve particular attention during your trial period. The lab’s further volume and three-band EQ adjustments produced very similar results to the initial setup, without improving the measured scores.
Overall, All-Day Clear earns a HearAdvisor SoundScore of 4.4 out of 5, an A SoundGrade, and a 2026 Expert Choice Award. Its overall lab score places it in the top 10% of OTC hearing aids HearAdvisor has tested, including older models.
About our testing: This review combines hands-on evaluation for HearingTracker with standardized laboratory testing from HearAdvisor. The companies are separate but have overlapping leadership, and author Steve Taddei is also HearAdvisor’s co-founder and lab director. HearAdvisor determines its testing methods and SoundScores independently of manufacturers; HearingTracker is responsible for this review’s editorial conclusions.
Understanding the results
HearAdvisor uses a standardized sloping moderate hearing loss and a KEMAR acoustic manikin. Using the same hearing-loss profile and controlled sound scenes allows comparisons across OTC and prescription devices. For All-Day Clear, both fits used a closed vented dome, standard receiver, and Automatic program. Initial Fit already included the app’s volume-and-clarity customization; Tuned Fit used lab measurements to guide further volume and three-band EQ adjustments toward prescribed amplification targets. The scores describe those tested setups, not a guaranteed individual outcome. The OTC averages include older tested models.
Speech in quiet
How clearly speech comes through in calm, one-on-one surroundings.
Speech in noise
Speech understanding against loud background noise — the toughest everyday test.
Own voice
How natural your own voice sounds while wearing the aids, without a boomy, plugged-up quality.
Music streamed
Sound quality of music streamed to the hearing aids over Bluetooth.
Feedback handling
Resistance to the whistling and squealing caused by acoustic feedback.
Farther down this page, you can listen to HearAdvisor’s recordings of All-Day Clear in speech-in-quiet, speech-in-noise, and music-streaming tests. Use headphones to compare the sound across the available recordings. These samples demonstrate the hearing aids’ processing on the lab manikin; they cannot predict exactly what you will hear with your own hearing loss and fitting. The HearAdvisor All-Day Clear review also has detailed results and recordings.
The HearingTracker Score
The HearingTracker Score goes beyond just sound performance and also considers value and everyday factors such as battery life, wearing comfort, Bluetooth connectivity, and design. The scorecard below brings those factors together; my experience with comfort, controls, and charging helps explain what the numbers mean in daily use.
A strong OTC choice if you value comfortable all-day wear, clear speech in quiet, and dependable Bluetooth streaming and hands-free calls. At $999.95 per pair before promotions, its limited fitting controls, basic charger, and weaker performance in noisy places are the main reasons to compare alternatives.
Key Features
Expert Review
I found All-Day Clear comfortable during prolonged wear, with no retention problems, and its Bluetooth connection was easy and stable. The hearing aids also felt well built in my hands. Those are meaningful strengths in a device you wear and handle every day.
The supplied charger is the compromise: it needs an outlet and was fiddly to load and unload. The app offers useful volume, program, and three-band EQ controls, but it lacks extras found in some competing apps, such as directional microphone controls and health tracking. I think All-Day Clear offers very good value for someone who prioritizes comfort and connectivity, even though about $1000 per pair is a substantial investment. If you need more fitting flexibility or a charger with a built-in battery, weigh those tradeoffs before buying.

Trial Period, Warranty, and Accessories
For purchases from Sennheiser’s U.S. store, the return policy allows eligible hearing-aid returns within 45 days of delivery. Keep the original packaging and accessories, and arrange the return within that window. If you buy elsewhere, check that retailer’s policy.
All-Day Clear is IP68-rated for resistance to dust and water (still, we recommend you keep them out of the water). They come with a standard 1-year limited warranty. When checking out, you’ll also be offered 1, 2, and 3-year extended warranties for about $27, $54, and $82, respectively. If you click the “No Extended Coverage” option, it does not remove the standard 1-year limited warranty included with the hearing aids. (See warranty information for details on coverage.)
Sennheiser’s main All-Day Clear accessory is the TV Connector, sold separately for $349.95. It streams TV or stereo audio directly to the hearing aids and includes the TV Connector, Micro USB cable, wall plug, optical/TOSLINK audio cable, and analog 3.5 mm audio cable. Other spare parts include replacement eartips and wax guards, generally listed at $15.95.

Final Verdict
For me, All-Day Clear’s appeal is straightforward: it sounds good, feels comfortable, and makes everyday streaming and calls easy. I’d put it on the shortlist if those are your priorities and you’re comfortable setting up hearing aids in an app.
The basic charger and limited fitting controls hold it back, and noisy conversations are a weaker use case. At about $1000 per pair, I’d weigh those compromises against entry-level prescription options. Here are my main pros and cons:
Positives
Strong Performance: All-Day Clear earned an A SoundGrade from HearAdvisor, which reflects overall strong objective sound quality performance. And in my own real-world testing, I’d say that holds up. These OTC hearing aids sound good, although noisy settings remain a limitation. Their overall HearingTracker score is among the highest for rated OTC hearing aids. Comfort and Handling: I could wear them comfortably for long periods without retention problems. Onboard buttons and app controls provide practical ways to make everyday adjustments. Modern Features: From a feature standpoint, All-Day Clear checks many boxes. You’re getting all-day rechargeable battery life, app control, Bluetooth streaming, and more. Past sales around $799 improved its value; the current manufacturer price is $999.95 before promotions.
Negatives
Basic Personalization: The “My Sound Profile” onboarding is…fine. But compared to some other OTC options, it feels a bit limited. You’re choosing speech preferences; the app doesn’t measure hearing thresholds or accept an audiogram. Use the trial period to check whether these controls give you enough clarity in your everyday situations. Basic Charging Case. The charging case feels behind the times. There is no standard internal battery for on-the-go charging, the hearing aids are locked-in mechanically, and they use micro-USB. It’s also larger than many other chargers. Overall, the charger design could use an update. Price. At about $800 to $1000, this is still a significant investment. That doesn’t mean it’s a bad value, but based on my clinical experience, I can tell you that price point is still a barrier for a lot of people. As I’ve mentioned in many of my videos, some clinics offer prescription hearing aids around this price range.
