I had a nice pair of in-the-ear phones that I used when I was getting my face elecrolysedzapped. About 200 hours worth. However, since then, I started wearing hearing aids, so I can't use in-the-ear phones any more. I now have some nice comfy over-the-ear headphones. I wish they had a longer cord, but not enough to actually go wireless.
My hearing aids will do Bluetooth, so I suppose I could sync to them and listen that way. But that won't disable the speaker, and part of the appeal of phones is the privacy and not disturbing others.
