This one is at least as good as the best one I have ever used in my office - which I usually end up spending over $ 100 for. When I took them out of the box they paired quickly with both an Android device and then (after forgetting that pairing) an iPhone. It could be operator failure :) I wanted some wireless earphones for a while but nothing was catching my eye for my budget. Like always looking for ?? everywhere. He does not wear them for extended walks because that means he may be running and I want him in a shoe that is more secure for that. So this purchase has me now feeling totally ripped off by buying this garbage from MAXELL. I have to say though, when my foot exspands after standing my toe hits the top, but that is not a problem at all because they are stretchy. I wore other the other pairs out. I saw preservision on TV & they advertise NO BETA CAROTENE so naturally Ibought them because I dont want to go blind from macular degeneration or get lung cancer from beta carotene Today my daughter started to read the ingredients in preservision & lo & behold there IS beta carotene in this product.
