4.5 Great Price, Great Quality LordMoolybap | 14/12/2009 | See all LordMoolybap's reviews (1) I use these headphones every day when I am walking to work . I have had them for 7 months now. The battery life is very good and the build quality is sturdy.You can use the controls which are next to the ears to go forward and backwards on tracks and change the volume. I often press the wrong button so stick to the controls on the phone I use.I use the Sony C902 and sometimes this has problems streaming the sound to the headphones, this causes it to occasionaly cut out and then try to catch up by speeding the music up a little. It doesn't happen too often though and is a fault of the phone really. (Although make sure your phone is meaty enough to stream the music via bluetooth).All in all these were a great price and I don't know what I would do without them!
