Here’s a rather long review about these on the Bose website from a lady who has single sided deafness due to an acoustic neuroma. Sounds very positive about them:
Rejoined conversations - got my social life back
The first thing the Bose salesman said was, "This is not a hearing aid." My husband said, "Good, because hearing aids don't work." I lost all my hearing on one side to a brain tumor, and lost a lot of hearing on the other side from other things. A hearing aid helped in a quiet room, but I still had to use closed captioning for TV and movies, and I couldn't join a conversation when there was even a moderate background noise.
We asked the Bose salesman if we could try out the HearPhones in the Apple Store a few doors down. Hundreds of people were milling around in there. He walked down with us. I stood across one of the big tables in the store. My husband spoke in a normal tone, and I understood him clearly. I spoke back, and he, with his normal hearing couldn't hear me over the din. Breathaking! We tried the food court and another noisy spot. No problem. My husband bought me a set for Valentines day.
We had dinner in a noisy Irish pub that night. No problem! We went to the movies. I dared to skip the closed captioning devise. No problem! TV? No problem. Phone calls? The Hearphones bluetooth made it no problem. I got my life back. Within two days my hearing aid gathered dust in the drawer.
It's also nice to wear a device that looks cool, sporty and powerful instead of an ugly little device that tries, but fails to hide, while apologizing for its own existence. People smile when they see my Hearphones. They ask about them; it starts a lot of conversations. They marvel when I tell them what it can do. Nobody smiles at a hearing aid.
Bose, if you're listening, I have a request. I'm still sound-blind on one side. I am co-chair of the San Diego Acoustic Neuroma Society, a national tumor survivors' support group. Almost all of us have single-sided deafness. There are hundreds of thousands more with other challenges leaving them with one good ear.
Please add a crossover feature, so sounds from both sides can be fed into one good ear. You would give us back the other side of our life.
P.S. The collar tends to swing sideways. Please consider adding a downward curve that would settle the collar comfortably over my shoulders so wouldn't swing around side to side. I can't exercise with them because they would fall off.
P.S. I couldn't comment on the durability because I've only had them for 7 weeks. They seem well-built.
