  • These are so comfortable that forgetting they are in is the biggest issue.
Style: All Day Clear Slim
I would recommend these to anyone that is looking to buy a pair of hearing aids. I bought them for my mom after she tried a number of the $200-$500 pairs and she loves the Sennheiser All-Day Slim Hearing Aids. She wears these every day, all day. After 5 months of daily use the biggest issue she still has is forgetting they are still in before a shower. It is so bad that it has become a running joke. According to her, the only reason she remembers to take them out is that she can hear the water too well. She is a frugal person, but after numerous attempts to find ones that work from all the online brands and a local hearing aid specialist I suggested we get her a pair of these to try. I have had Sennheiser products in the past and they were always great, so when I saw these I was excited. They are expensive, but worth the price because they are far cheaper than the few thousand dollars for a professionally fitted par. She wears glasses and was concerned about the comfort of the behind the ear style, but they work great with her glasses and don't fall out (she is extremely active). I was worried that as the household IT person I would constantly be fiddling with the app for her, but it is intuitive enough that she adjusts them as needed from her phone. Even though you can get them fitted professionally, we found it easy enough to do at home. A great feature that is often overlooked is that they are Bluetooth, so she can answer calls, listen to music and watch videos all from the hearing aids. The battery lasts all day and they are not heavy or overly large. She says that they have great sound for both hearing local noises and sounds from the Bluetooth connection. The only real negative is the price, but we found them on sale and it was a no brainer. In fact she has been watching for another sale to get a backup pair in case she accidentally does forget to take them out. She is constantly telling her friends "no, I am on my hearing aids and they are wonderful, you should try these as well" and she is constantly thanking me for getting them. They have truly been a quality of life improvement for her and us because she can hear us (especially her grandchildren that talk quietly) clearly and doesn't have to guess what we said. All in all they are a solid recommendation from me and my mom. ... show more

  • Returned
Style: All Day Clear Slim
I'm so disappointed in these hearing aids. I loved the sound, they were easy to connect to my phone and the price wasn't as bad as my older aids. I've worn hearing aids for 40 years, so I know good quality in sound, these were awesome. My disappointment is in the battery recharging connection. One side was troublesome for the 4 days I used them. It would start to charge and then would stop. This morning was the last straw, I went to put them in and one side was green and the other side red. No charging. It's too bad because the sound was so natural for me. ... show more

  • I like the way it looks on me
Style: All Day Clear Slim
The All-Day Clear App was easy to download and use. The hearing aids fits well and the appearance looks nice. Some of the features I to get use to, like to increase volume you have to quickly press the push button on the right hearing and to decrease you have to quickly press the push button on the left hearing aid. The sound is clear and overall I like the hearing aids. ... show more

  • I highly recommend the All-Day Clear Slim
Style: All Day Clear Slim
I was on the hunt for new hearing aids that had to check a few boxes and these do it all very well! - Full Android integration - Rechargeable - Quick and easy setup - Application easy to use - All-day comfort I highly recommend the All-Day Clear Slim. The first draw for me was full Android integration, no holding my phone up to speak into as with other brands, these have microphones built into the earbud style receiver and the audio is crisp and clear for in-person conversation and Bluetooth streaming. I really like the form factor too, the Slim version tucks behind my ear very well with or without my glasses, the slightly larger wire feels more durable than others I've used, these seem to have a bit more deeper (less tinny) tone than others I've used, and the larger earbud-style in-ear receiver is stout and very comfortable for all day long usage. This style feels much more natural to me with less of a plugged ear feel than the smaller ones I've used before. I've had store bought HA's with custom programming which is nice for people who need it or don't know what to expect or understand about getting used to integrating any HA's into their life. If you're patient and have an understanding of the adjustment period of getting used to HA's then these are a great contender for the over-the-counter (OTC) market. I really like the application and setup of these, it's quick and simple for do-it-yourself at home and gives you some simple adjustments. After the quick initial profile setup be sure to adjust the EQ to ensure these are really dialed in for you. Alternatively, you can pay for the additional in-office service they offer through a network of providers, make note that network isn't huge so be sure to check their website for details if that is something you need/want. Also, purchasing that extra service extends your warranty by another year too. I really like these are rechargeable and last all day. The only thing I dislike is the charging case itself. It's very large and only works when plugged into the wall. The case doesn't have an internal battery to allow additional charging on the go. These HA's do last all day so probably isn't a big deal for most but the ability to travel over a weekend with a smaller recharging case would have been perfect for me. The Slims also come with an additional small non-charging storage case which is nice. ... show more

  • Frustrating to use.
Style: All Day Clear Slim
Why did you pick this product vs others?: It had good reviews and it's nearly identical to its $7,000 twin from Phonak. Their customer service is outstanding. Which is why they got two stars. The product itself is frustrating, has very limited programming options and only offers three different sets of earbuds which are identical just different sizes and are elliptical which quite honestly doesn't make sense to me because my ear canals are pretty much round. Really couldn't work around the feedback, problems, background noise problems they were just frustrating to deal with. I did find something else that actually did a full hearing test as part of the setup and was a fraction of the price. ... show more
