They don't sound very good and are very tight on your head. Do youself a favour and get yourself something a little nicer. In this price range you can get nicer headphones or earbuds.
Comfortable. Good colour. The problem is that it's hard to tell when they are on or off (other than a tiny light), because they don't speak to the listener the way other bluetooth headphones I've used do. Connecting Bluetooth was easy because it makes a noise. They autoconnect, which is a nice (you don't have to put them in pairing mode first). The sound quality for music is great.
