I have been 90% deaf in my right ear for 40 years. Then one day I came across a weird looking set of headphones and put then on the normal way, trying to insert into to ear, and it just did not "fit." But a really weird thing happened--I could hear in my right ear. I was hearing STEREO again!
I then digged into this and found out they were Bone Conduction headphones--something I never knew existed. They broke because they were all rigid, and so I looked for another type, and found these with a flexible backing, and for just $50 too. I went for it in a flash. it is a no-brainer for that price
These are great. I listen mostly to talk and speech at work so I do not care about great musical quality, but the sound quality I hear is just perfect. And who cares for rich musical sound with Bone Conduction because your ear is free to hear the ambient noise all around you as you listen to the headphones --a real PLUS because I can listen to them and still hear everything normally happening around me. No vibration, fit nicely, flexible. Can't comment about call featues yet.
It is so weird to hear in stereo even though my right ear somehow got damaged a long time ago.
