My new HAs

I haven’t had new hearing aids in years and I’ve been so positively overwhelmed with my new aids I’m going to be singing some major sweet notes in this review. I wish I hadn’t waited so long for my new hearing aids but I’m so very glad that I got them now. They work so much better than any other hearing aids I’ve purchased that not only am I happy, but I also don’t have a single negative issue to suggest your company work on improvements. These hearing aids are the most amazing hearing aids I’ve ever used. For the first time in my deaf life I’m not unhappy about being a hearing aid user. Thank you for making hearing aids that are comfortable, easy to use, connected to my cell phone, and what I love the most; controlling the volume in my head and adjustments (nobody else can hear what I’m listening to, tv or phone calls). Thank you for making my disease so much easier to deal with out in the world and for using on the phone. 👍

Constant connection issues

Once the HA are connected it seems fine but after charging the HA overnight the connection on one or both HA is lost. Then the hokey pokey begins. I usually just give up. Also, the charging case appears to be needed in any attempt to reconnect the HA to the app. That means one is to always have the charging case available at all times? Not taking it with me while out all day. Very disappointed and frustrating Update 02/05 hit or miss on phone connection. Most of the time one or the other will show up as disconnected. On the plus side had HA’s changed to control volune, right up, left down. Another minus, cannot answer a phone call bia the HA’s as I could with my Phonak HA’s. So if my iPhone is in another room I need to go find it to answer a call. If Phonak can. Answer via the aids, why not Resound? App is less than average. 3/27: the app rarely stays connected to the aids. Most every morning need to do the Resound hokey pokey, in case, out of case, settings, pair, in case, out of case, yada yada … ridiculous. Would like these hearing aids and the Phonak app which worked all the time.

The developer response for the connection issue doesn’t provide any answer to the connection dropping issues. How to connect is explained in the app or other. I rarely use the app because of issues. As long as they stay connected to the iPhone is all the matters.

Not perfect

My first pair of behind the ear resounds I bought three years ago. They worked fine for a while and then they started fading in and out with sound correction. I finally got my provider to send them in and there was a controversy Esther were there there was a problem. But I finally convinced them that there was and apparently they tested it for that and I got I believe a whole new unit inside my old ones was probably updated. It has worked quite well. I still have problems hearing but it’s probably not the hearing aid it’s probably just my physical condition. My big problem is they no longer will communicate with my iPad and only my iPhone I’ve tried rebooting putting on another app all to no avail I will put up with that, but it’s not the best situation.
