Customer Ratings & Reviews

Sennheiser support is the worst! I have been trying to get replacement All-Day Clear Slim Wax Guards for six months with no luck. Links on their website are broke and they will not respond to repeated support requests. My aids are just over a year old.

This product has greatly improved my life and I am thankful for the help I received choosing it

Review for Sennheiser - All-Day Clear Slim - OTC Self-Fitting Hearing Aid I was looking for three main features in an OTC hearing aid: rechargeable, Bluetooth connectivity, and quality of sound. I found them all in these hearing aids. Sennheiser is world famous for their audio products, so I was banking on them putting their name on these *only* if they met strict quality standards. I was not disappointed. They’re light weight and easy to handle. Since they have a behind-the-ear component, the portion that goes into your ear is small and comfortable. The part that goes behind your ear is nearly invisible and has simple controls for changing volume and taking phone calls. The connecting wire is soft, but bendable and makes it easy to fit the aids to your liking. They feel secure, but with their open air design, not like some aids that feel stuffed in your ears. Also, they come with three earpiece sizes to fit each ear nicely. Connecting the aids to your phone is easy with the app, which is also very straightforward. Once paired, a simple hearing preference test locks in your settings until you want to change them. The Bluetooth connectivity lets you listen to music (with quite nice sound quality!) or make and take phone calls. It’s important to note that the 16 hour battery life pertains to using the aids for hearing assistance, but using Bluetooth will only give you a few hours of battery life. Charging the aids is easy with the enclosed charging case. Red, yellow and green indicators keep you up to date on charging progress. Taking the aids out of the charger turns them on and connects them to your phone. The app lets you adjust the overall volume or set it separately for each ear. You can fine tune the equalization with bass, mid tone, and treble sliders. Audio signals let you know when the batteries are running low. Finally, due to their construction, sound is enhanced without sounding “canned” or artificial. The mixture of sound traveling directly to your ears combined with the amplified sound comes across as very natural.

In the box: • Left & right hearing aids • Charging case • Small, medium, & large eartips (1 pair each) • Extra wax guards (x6) • Cleaning brush (inside charging case) • Carrying case • Power adapter (5v 1A) • Charging cable (USB-A to USB-C) • User’s Guide (and other printed materials) Setup: The setup instructions advise that the hearing aids be charged for at least 3 hours before first use. After some initial challenges, the hearing aids were successfully paired with my iPhone. Of note, there are 3 devices that may show up in your phones Bluetooth settings. The main device (All-Day Clear Slim) is the one that controls the connection with the phone. The other two (L – All-Day Clear Slim, and R – All-Day Clear Slim) are low energy connections by which the Sennheiser app controls the settings in the hearing aids. These low energy devices may appear in the list of Bluetooth devices on your phone, but connections to them are controlled by the app (i.e., you do not need to manually connect them in your system’s Bluetooth settings). The setup process is guided by the All-Day Clear App (available from the Apple App Store and Google Play Store). Early in the process, you will need to go to your system Bluetooth settings (without closing the Sennheiser App), connect to the All-Day Clear Slim device, and return to the App to complete the setup. The App will control pairing of the left and right earpieces. Once paired, you will be guided through setting up a sound profile. The profile customizes the volume and frequency settings. When your profile is complete, you can close the App. The hearing aids will retain the settings in the profile even if the App is closed or the phone is out of range (or turned off). By default, connectivity on the iPhone uses an adaptive Bluetooth protocol. You can disable adaptive Bluetooth in the App if you encounter connectivity issues. The hearing aids must be powered off then on for a change in settings to take effect. I was also able to pair the All-Day Clear Slim with my android phone, but couldn’t connect with it and my iPhone at the same time. Fit & comfort: I wear reading glasses and frequently put them on and take them off and was initially concerned by the behind-the-ear design. The thin ear loop and slim unit design made this a non-issue. The in-ear pieces are very small and comfortable. So much so that after about an hour I forget that they are there. The same is true of the behind-the-ear pieces. I would not notice them if not for the audible differences in my perception of the world around me. They do get a bit tiresome at the 6-hour mark, but this is far longer than I have been able to wear other OTC hearing aids. Performance: While some extraneous noise is amplified, there appears to be a substantial amount of signal processing going on. I hear more detail in my environment. Nonetheless, it will take time for my brain to develop some new filters for the for the unwanted sounds (e.g., fans, the TV in the next room, etc.). There are instances when the hearing aids would lower ambient sound in one or both ears. This happens predictably when an auditory notification is generated by a connected phone. The hearing aids switch the audio source from their own microphones to the phone. After the signal from the phone ends, there is a slight delay before the hearing aid microphones re-engage. The transient (<0.5 seconds) lowering of ambient sound in the absence of a phone notification is unexplained, but only seemed to affect background noise, not conversations. Volume on the hearing aid can be controlled with an 11-step slider. You can adjust both together or split the control and adjust volume for the left and right separately. There is an 11-step, 3-band equalizer in the “Fine Tune” menu. It’s a nice feature, but not well implemented. Once you select Fine Tune to get to the equalizer, you have no other option than to select “Done”. If you have made changes, there is no way to quit without saving. If you don’t like the changes, you have to remember the original settings and reset them before pressing “Done”. Equalization settings apply to both earpieces even when you choose to split the volume controls. Battery life is quite good. Approximately 12h of use took the batteries to 40% equally in the left and right earpieces. Phone calls through the hearing aids were a major disappointment. Incoming sound quality was clipped, particularly in a noisy environment. Unlike streaming audio, the microphones must remain active when on a call. This sets up a bi-directional communication channel with the phone at which the All-Day Clear Slim is not well suited. Once paired, the App can still communicate with the hearing aids without having the main Bluetooth device connected. I actually prefer using the hearing aids without the phone connection. I can still adjust them with the App and there is no competition between the microphones in the hearing aids and phone notifications. I simply use my phone as I have for years. In this scenario, the hearing aids help, rather than hinder, calls. Hearing aids remain on and Bluetooth connected even when they are in the charging case. They must be turned off in order to disconnect. Placing the hearing aids in the charging case should turn them off regardless of whether the power cord is connected. It would have been nice if the charging case included a battery so that a wired power source was not always necessary for charging the hearing aids. There was one occasion when the left hearing aid would not come on and would not charge in the case. Holding the button down for 30 seconds reset the unit. I had to do the same on the right and go through the setup process again. Overall: I have tried a number of in-ear OTC hearing aids and, with rare exception, find them unhelpful at best and annoying at worst. The Sennheiser All-Day Clear Slim has convinced me that it is possible to make an OTC hearing aid that actually improves my hearing. Streaming audio is OK, but no match for good quality Bluetooth earphones. These are good hearing aids, but do not function well as a headset for making calls. A firmware update to turn the hearing aids off when in the case would be a big improvement and keep them from draining unnecessarily when not in use.

This is my second style of OTC hearing aids I have tried and I have quickly noticed some positive differences. The other set I have is more of a "ear bud" style which I did originally like because they looked like regular wireless ear buds and they were pretty small. However, battery life wasn't ideal for all day usage with those more of just a pop them in when there is a reason to hear better kind of set-up. Originally I was hesitant for this style thinking that they would be a little unsightly for my age bracket (sub 40 years old). While I probably wont be gaining any style points at the club these are barely noticeable and substantially more comfortable to use over the entire day. Having the wire go from the ear piece to the body behind the lobe provides good weight distribution and better comfort. I had no issues using the medium size ear insert that comes pre-installed but they do also include a small and large set for other ear shapes. These offer much better battery life than the ear bud style, I would imagine also being contributed to the design to allow more space for a larger battery. The charging case is pretty large and bulky, but it does use USB-C thankfully, they do also include a smaller leather carrying case. Neither the charging case or the carrying case offer any on-the-go charging functionality. That has not been a necessity for me yet, I am able to get 12+ hours of use in on a single charge. Sound quality has been good, not very harsh in the way it amplifies and makes it easy to focus on voices and not flood you with background noise. Overall I have been very happy with these as finding something that fits well is extremely important for how good they will function. Sennheiser is a brand I have been familiar with and trust for quality, so far these hearing aids haven't disappointed yet.

This hearing aid was purchased for my husband.He had a lot of problems with it.

No connection if no network data. Good for distance but not nearby

I have several Sennheiser headphones and earbuds and I’ve always loved the quality, comfort and richness of sound so I was intrigued how Sennheiser would approach the new over the counter hearing aid market since Sonova acquired them. Sonova is a leading provider of hearing care products and with the All-Day OTC hearing aids you can definitely see and hear the influence. These are the most comfortable hearing aids I’ve worn, including the pricey prescribed set I have owned for a couple of years. They fit more like earbuds with full sized tips that fit snuggly in the ear canal and they don’t tickle my ears like my prescription set. It comes with medium sized tips installed but included are smaller and larger tips so you can fit to your ear. Setup was a breeze. Install your flavor of the All-Day Clear app from Google Play or Apple Store and start the pairing process. Once paired you set up your profile. They use a canned conversation to listen to and you adjust volume, tone and clarity as needed for your hearing situation. I have more hearing loss in my left ear and the app allows you to fine tune by splitting the volume controls for each ear. Even more importantly, something missing from most over the counter hearing aids, is the ability to listen to music and have audio for phone calls. That is a huge plus over other units. As with all hearing aids the noise coming in from the built in mics is a bit tinny but you get used to it very quickly. Sound coming in via Bluetooth is crystal clear and full bodied, meaning that it’s not much different than listening via earbuds. I expected no less from Sennheiser. Using the phone app you can make adjustments on the fly. In my office environment we have high levels of conversation at times so it’s great that the app allows you to dial in the volume you need so you can reduce the amount of ambient noise. I usually have to dial it down a lot at times to reduce the distractions nearby. The things I wish were different… It would have been a good feature to have and option for a longer stem. I wear glasses and with the size of my ear the body rides a bit higher and contacts the stems of my glasses. I bit of extra length would allow the body to ride a bit lower behind the ear and not come in contact with the stems of my glasses. I know the push is that these hearing aids have a 16 hour battery life but they miss the boat that the charging case does not have a battery. Case must be plugged in for it to charge the earpieces so you can’t charge the hearing aids if you are on the go. At the price point and the sheer size of the charging case they should have included a reserve battery for charging on the go. I would have opted for that rather than the padded carrying case, nice touch but unnecessary. Give me a battery in the charging case please!!!

Set up was easy. The app wasn’t very good, not many settings to tweak them and it kept resetting back to the default settings. The sound quality wasn’t awful but it only worked as an amplifier, everything more than about 5 feet away was hard to hear, everything up close was super loud, the button clicks on the tv remote sounded like I was slamming a pot lid on the counter. Not worth the money.

Possibly the worst customer service on Sennheiser side I’ve experienced. I dont usually leave reveiws but i couldnt even connect to the app. Sennheiser also tried helping and they didnt even know what the issue was. Im guessing if i was able to connect it would have been good but i have never been as frustrated with a piece to tech as i was with this. I just want to hear lol

I recently had the opportunity to try the Sennheiser All Day Clear Slim product and I am happy to share my positive review about it. First of all, I must highlight the exceptional sound quality it offers. The bass is deep and powerful, while the treble is clear and precise, providing a most enjoyable listening experience. Plus, its slim, sleek design makes it very comfortable to wear throughout the day, without putting undue pressure on my ears. I'm also impressed with the battery life, which allows for extended use without having to worry about constantly recharging. Finally, I appreciate the noise reduction feature, which allows me to fully enjoy my music by filtering out external distractions. In short, the Sennheiser All Day Clear Slim product is a perfect choice for all women wishing to combine style, comfort and exceptional sound quality.

It is nice to have hearing assistance and also be able to answer the phone or listen to music without having to switch between devices. It is a bit more obvious that I have something in my ear than other hearing assistance devices I have used, but most people assume it is an ear bud. It is convenient to be able to adjust the different levels if I want more or less bass for example I can use my phone to dial in when seems right for me. Not having something in my ear canal makes it more comfortable, although more obvious to others. The set up took a little bit, but was doable. Overall it is nice to have a little bit of assistance when I want it without having to go get an ear exam. I can adjust the settings depending on my environment. It is nice because if I know there is someones voice that I want to hear I can work at adapting the settings to be ideal for that voice to help me pick it out from the surrounding noises. The background adaption is a nice feature that helps balance levels.

The Sennheiser All Day Clear is an impressive product designed for those looking for clear audio and comfort over extended periods. The sound quality is top-notch, offering crisp, balanced sound with clear midrange and detailed highs. The noise-canceling features also work well to create an immersive listening experience. Comfort-wise, the design is lightweight and ergonomic, allowing for long hours of use without discomfort. The battery life is robust, offering all-day use on a single charge, which is perfect for people who need headphones that last through work or travel. The microphone quality for calls is also clear, making it a good option for those who frequently use their headphones for communication. The connectivity is stable, and the controls are intuitive. However, while the audio quality is excellent, some users may find the bass a little underwhelming for genres that demand deep lows. Additionally, the price may be on the higher side for some buyers. Overall, the Sennheiser All Day Clear is a solid choice for anyone looking for high-quality sound, long-lasting comfort, and reliable performance for daily use.

The Sennheiser - All-Day Clear Slim - OTC Self-Fitting Hearing Aids have been…well, they’ve been a blessing. To be able to hear more in a social setting is wonderful. I’m using the phrase, “I’m sorry, what?” much less. I appreciate that. My family appreciates that. The All-Day Clear Slims, like any hearing device, will take some time to get used to. Incoming sound/voices seem to have a bit of a ‘canned’ quality. I figure that’s going to take time for my brain to work out — and for me to fine tune as time goes on. One thing that has made this experience much easier to deal with is the setup and controlling capabilities of the All-Day Clear mobile app. It was one of the least tedious, easy setups that I have experienced with OTC hearing aids. Thank you, Sennheiser. Over time, I can only imagine that I’ll be using the app less and less. Right now, it’s great to have total command as I continue to become familiar with them. I can fine tune balance, volume, and tone (with an EQ) in either a split fashion, or both left and right together. My set has two sound settings — Automatic, which seems to adjust incoming sound based upon your surroundings (like in a constantly changing social setting), and what Sennheiser calls the Live Music setting. This setting seems to take everything in just as it is. I have found myself having the Automatic setting on during most of the day. When I’m relaxing in the evening and watching the TV or a movie, I prefer the Live Music setting…fewer sounds/voices dropping out and then returning. Everything seems to stay more constant. This is all kind of hard to explain. You need to experience it yourself. There are a couple things I wish were different — I wish the charging case had an internal battery to charge the aids overnight. As it is, the case does need to be plugged in via USB-C. I wish the receiver buds were tan or semi-translucent instead of black. Less noticeable. I wish the connective wire from the main body to the ear bud was just a tad bit longer — but that’s just the ‘design’ of my earlobe. Even with all this in mind, these are darn good hearing aids. Try ‘em out. You’ll want to check with Sennheiser, but I believe that they offer a 30-day trial period…and with these, you don’t have to buy any hearing aid batteries ever again!

Overall, the Sennheiser All Day Clear Slim is a versatile and reliable product, offering excellent sound quality, comfort, and functionality at a reasonable price.

I have been looking at OTC hearing aids for a while, I am a retired police officer. And for 20 years I was a firearms instructor, the majority of that time I only used the soft foam, moldable in ear hearing protection. Now I’m paying the price, my hearing is not what it used to be. I first off want to mention how well these are packaged by Sennheiser, the outer box was a mess, it looked as if it had been crushed and I was worried about the product inside. But once I opened it and removed the inner box I realized they were not, due to the fact that Sennheiser put forth a lot of effort in packaging these hearing aids. JOB WELL DONE1 Before I received these I downloaded the All-Day Clear app and registered for a new account. When they arrived I was surprised that they were 77% charged. The initial setup w/ the app and the hearing aids was very easy. It took about 2-3 minutes and I had them connected to my phone by bluetooth. I took the time to try on the included soft, gel tips to find just the right fit for me. I settled on the medium in my left ear and the small in my right. My problem is that no matter what I do, whether its w/ these Sennheiser All-Day Clear Slim fearing aids or just in-ear headphones, God made my right ear different from the left as far as the canal is concerned. My point is I never have a problem w/ my left ear, but my right ear after about an hour or so, I begin to experience ear fatigue. And it gets to the point that I have to remove it. It was the same w/ these. That is no fault of the company, it’s just me. As far as the product, its is VERY well made! These are lightweight, that was the first thing that I noticed when I removed them from the case. My wife and I rode our golf cart after I had the tips on and the hearing aids wire adjusted. I chose the wind noise reduction setting, but I still had a lot of wind noise in both ears, not a big deal but it was noticeable. When we arrived at home my wife was doing laundry and I was reading/listening to the television. And I had the volume set to what I “normally” have it set on and immediately I had to turn it down. I realized then that I really need hearing aids. I was amazed, because I could hear. My wife came out of the laundry room and asked why I turned the volume down and I told her that it was a bit overwhelming. And it was/is. I was hearing “noises” I had been missing. I was shocked to hear the water discharging from the washing machine, I had never heard that. I heard my wife running water in the kitchen sin, again, I hadn’t heard that. And then, the ear pain started and I removed them for the night and charged them. I went to Church the next morning and I was pleasantly surprised how well I could hear, again, I heard sounds, noises, voices, etc., that I hadn’t been used to hearing. And the adjustability on the app makes fine tuning these to fit your need and surroundings so simple. JOB WELL DONE! The fit, other than my right ear is great. No one has noticed (if they have they haven’t mentioned it) that I have these in. They are sleek and when Sennheiser says “Slim” they aren’t kidding. I was pleased how well they stayed in and allowed me to hear again. Take the time to mold the wire to fit around the front part of the ear and they are truly not very noticeable. The soft case that Sennheiser includes in the package is a great benefit for me, I put it in my pocket and when the ear fatigue starts I will take them out, I’ve tried leaving the left hearing aid in, but its hard to explain but I just don’t like the results, its as if I’m turning my head to the right to compensate and it becomes overwhelming. My hope is that the more I wear these and get more accustomed to that “overwhelming” feeling that my ear fatigue will go away. Because these Sennheiser All-Day Clear Slim have opened my eyes to how much I had lost in my hearing. JOB WELL DONE!

I have to say that I am really impressed with the Sennheiser All Day Clear Slim product. With my regular small hearing losses, it is often difficult for me to fully enjoy my favorite music or follow a conversation clearly. However, since I started using this headset, my life has really changed. Its thin and lightweight design makes it extremely comfortable to wear all day, without any discomfort. Additionally, the exceptional sound clarity I get from these headphones is simply amazing. The bass is powerful and deep, and the highs are clear and crisp. Even when I'm in a noisy environment, the headphones manage to filter out the noise and give me a great hearing experience. I am truly grateful to have discovered the Sennheiser All Day Clear Slim, as it has improved my quality of life significantly. I highly recommend it to anyone with hearing problems as it really does make a huge difference.

These headphones deliver exceptional sound quality, with deep bass and clear treble, allowing me to fully enjoy my favorite music without compromising my hearing health. Plus, its slim and lightweight design makes it extremely comfortable to wear throughout the day, without putting undue pressure on my ears. I'm also impressed by its durability and long battery life, making it an ideal choice for everyday use. In conclusion, the Sennheiser All Day Clear Slim is a highly recommended product for people with hearing problems, offering both exceptional sound quality and comfort.

Excellent: the performance. Vastly improved my hearing watching TV, movies, in restaurants, social gatherings - both indoors and outdoors. The app had short learning curve, easy to use, accomplished all I wanted, once it was installed, installation was an exercise in futility. I was unable to use my apple email addresses, iCloud in that a 2 step process required my receiving and entering a verification code. I was unable to receive the code despite using 3 different Apple based emails. I had to phone the help desk and their suggestion was to use a gmail address. I did, it worked, all went silky smooth. My issues are with the aesthetics. The portion of the hearing aid that goes into the ear is a prounounced BLACK color. It should be a lite color or clear color rather than the eye catching black. The wire that loops over the ear is just thick enough to also stand out. I have another brand of Hearing aids that use the same format. The ear inserts are almost unnoticeable, and the wires are of a narrower diameter and barely visible. The aids charge quickly in their case, hence these aids are more desirable than my other aids where I am constantly replacing batteries. I also love taking cell phone calls with the aids being the receiver. If the 2 changes were made by the OEM, these aids would be 5 star!

As someone who has experienced both the frustration of hearing loss and the challenge of finding a suitable hearing aid, I was eager to try the Sennheiser All-Day Clear Slim Bluetooth Hearing Aids. These OTC devices promise a blend of advanced technology, self-fitting capabilities, and an elegant design—all crucial features for today’s consumers. The self-fitting option and programmable sound have empowered me to take control of my hearing experience without the need for frequent professional visits. For anyone seeking an affordable, high-quality OTC hearing aid that blends modern technology with user-friendliness, I highly recommend giving these a try. Sennheiser has set a new standard in the world of hearing aids, making them accessible and enjoyable for all.
