Behind the Ear

In August 2023, Sennheiser unveiled a new OTC hearing aid expected to compete with industry leaders like Bose, Sony, and Jabra. 

Sennheiser All-Day Clear is a full-featured hearing aid with Bluetooth streaming, hands-free calls, an onboard hearing test, and easy to use app. 

You can choose between a standard or Slim form factor. The insides of the devices are virtually the same, while the outside form factor changes by style. 

Read on for our full unboxing and review and review All-Day Clear against the Soundly Scorecard. 


In 2022 the legacy headphone and speaker manufacturer, Sennheiser, was purchased by the world's #1 hearing aid maker, Sonova. The move left some people scratching their heads until Sennheiser unveiled plans to join the over-the-counter hearing aid market earlier this year.

The move is significant because it adds another top brand and hearing powerhouse to the growing list of OTC competitors. Read our full guide to OTC hearing aids here

What makes All-Day Clear Special? 

For starters, Sennheiser All-Day Clear offers top-tier sound-processing technology for less than $1,500. The same underlying technology is $5,000 or more at local clinics. 

Sennheiser All-Day clear is an especially good choice for Android users. The device is one of only a couple OTC hearing aids that streams to both iPhone and Android (the other one is Lucid Engage). 

This product is unique because you can program the hearing aids from your smartphone and save thousands on the purchase price. It's the first time that Phonak and Unitron hearing aid fans can get a similar product direct-to-consumer.  

Our Take

Our team tested All-Day Clear and compared it with Sonova's flagship brands - Phonak and Unitron. Our verdict? All-Day Clear has a few missing bells and whistles (more on that below), but the differences are not dealbreakers. The perfect candidate for All-Day Clear has mild-to-moderate hearing loss, is comfortable using a smartphone, and wants Sonova-made technology for a budget price.

Based on our reviews, this hearing aid is the most complete offering in the over-the-counter market so far. You’ll pay a bit more than some OTC competitors but the prescription-grade sound-quality is probably worth it. 

Pros 👍
  • Premium technology for less than prescription channels
  • Bluetooth streaming and hands-free calls (Android and iPhone)
  • Comfortable all-day form factor

Cons 👎
  • More expensive than some OTC competitors  
  • Charger must be plugged in to work
  • Less precision in programming than prescription devices

  • The form factor of Sennheiser All-Day Clear is comparable to leading prescription hearing aids like Phonak Lumity

Pricing and Process

All-Day Clear and All-Day Clear Slim are available online through Sennheiser's website for $1,399.95 and $1,499.95, respectively. 

Sennheiser devices ship directly to your home, where you can pair them to a smartphone and customize them to your hearing loss. You can then use the app to make fine-tuning adjustments to frequency, volume, and program. See below for our full review with screenshots of the self-fitting process.

All-Day Clear Vs. All-Day Clear Slim

Your decision between models is about two things - comfort and form-factor. 

Both devices are identical on the inside. Battery life, sound processing and streaming capabilities are all the same regardless of model. 

We found that the smaller All-Day Clear receiver in the ear was more comfortable than the larger piece that comes with Slim. 

The Slim form-factor looks more unique and modern but isn’t significantly smaller than the non-slim version. 

We recommend that most customers opt for the lower-priced non-slim option.

Sennheiser is unarguably one of the elite names in audio. Musicians and audiophiles love the brand's purist approach to sound, and Sennheiser's $60K headphones have made a habit of going viral on YouTube for invoking big feelings (even tears) in audiophile listeners. 

So when hearing aid giant Sonova purchased Sennheiser in 2022, I got excited. A little over a year later, Sennheiser (under new ownership) officially joined the OTC hearing aid market. The brand released a conversation boost product called Conversation Clear Plus earlier in 2023. That first product was a headphone, hearing aid hybrid but didn't really compete with traditional hearing aids. All-Day Clear is Sennheiser's first bonafide hearing aid, and it's pretty great. 

For this review, I got my hands on both the Slim and non-Slim versions of the product and put them through the paces. Here's how it went. 

Sennheiser All-Day Clear Unboxing

Sennheiser offers two models of their All-Day Clear hearing aids. One is called All-Day Clear and the other is called All-Day Clear Slim. I got both pairs to compare them side by side.

The only meaningful difference between the two models is form factor. Slim is skinnier and longer while the non slim version is smaller overall.

Unboxing All-Day Clear and All-Day Clear Slim

Interestingly, the Slim version of the product has a chunky rubber earpiece, while the non-slim version has a standard open-fit ear tip.

I reached out to Sennheiser to learn more about the larger design on the Slim version, and they shared that some customers might enjoy a more sealed-off earpiece for sound-quality reasons.

Personally, I prefer the smaller ear tip for comfort and appearance.

Below is an image of both products in my ears. You'll note the larger black piece and the slightly longer body on the left.

Trying both versions of All Day Clear hearing aids

After unboxing the product took some time to try each of the extra dome tips and find the one that is most comfortable for me. Note that dome tip changes are only possible on the All-Day Clear (non-slim) version.

Both devices come with a recharge case that must be plugged into the wall while in use. The recharge case is simple to use but I did notice that Sennheiser opted for contact-based charging instead of induction charging. Not a big deal to me, but slightly less premium than top prescription devices on the market.

Programming and App Controls

Once I had my new Sennheiser hearing aids out of the box, it was time to connect them to my smartphone and program them to my hearing loss.

Step 1: Download The App

The first step was simply to download the All-Day Clear app. Just search "Sennheiser All-Day Clear" in you Apple or Google app store and hit download.

Step 2: Bluetooth Pairing

Open your newly download app, choose the version of the product you purchased and follow the instructions to connect your hearing aids and phone via Bluetooth.

Step 3: Create a Sound Profile

All-Day Clear is an over-the-counter hearing aid. That means you'll program your devices from home through the smartphone app.

Sennheiser guides you through this process in a few simple steps. First, you'll listen to a recorded track and choose the volume and clarity that is most comfortable to you.

There's no secret here, just pick the settings that sound best. You'll have more opportunities to customize things in the next step.

Step 4: Control Your Hearing Aids

Once your hearing profile is set you'll have access to the main app controls. Some of the key key features include:

  • Volume control
  • Split volume control (left and right)
  • Equalizer control (bass, treble, mids)

The app is pretty minimal. You can turn on wind-noise reduction or opt for a music setting which makes live music sound more natural. Otherwise, there's not a whole lot more to it.

It's worth noting that you can control your hearing volume and programs using onboard buttons on the device as well. I regularly use those buttons throughout the day when I need additional volume or want to turn down a loud environment.

Final Thoughts

So the big question: is All-Day Clear worth a try? 

I'd say yes if you have mild-moderate hearing loss and don't mind a DIY programming approach.

All-Day Clear has the best sound quality I've heard in a self-fitting, over-the-counter hearing aid. I've spent time wearing Sonova's flagship Phonak Lumity, and while the bells and whistles of Lumity are undeniable (better customization, charger, and app), All-Day Clear is cut from the same technological cloth - at 1/3 the price.

Is All-Day Clear perfect? No. But it might be the strongest mid-priced, OTC product on the market as of 2023.
