Review on Criacr Bluetooth Headphones: V4.1 Mini Invisible Wireless Earbud, 6 Hours Playing Time, Built-In Microphone & Hands-Free Call - One Pcs ONLY (Black) by Quinton Wonsley

Sharp looking, and good sounding. Very comfortable, though a bit heavier than some others. Decent battery life between charges.Mine had a problem with one of the control buttons: the down volume (which doubles as a previous song control, depending on how long one depresses the button) would often -- but not always -- cause the previous song to play instead of reducing the volume. I contacted the seller and after confirming the problem, issued a credit right away. Good customer service.
