Review on Bluetooth Wireless Earphones Sweatproof Headphones Accessories & Supplies by Jonathan Jensen

Communication quality is decent; I would say "excellent", but the headphone constant needs to be adjusted. even after I put it in a place where it lies well and I can hear clearly. As my head moves, the earpiece begins to slide off my ear and rotate slightly, requiring it to be tilted again; with a button to answer calls (and hang up) on the bud itself. right where you place your finger to insert the rubber piece into your ear. easy to hang up accidentally. Good sound, but the piece does not appeal to my ear.
