I bought this yesterday and used it after charging. Pairing was very easy and once my music was on my Blackberry it played instantly. Sound quality is very good. I like the extra bass as some of these headsets sound flat. I am going to use this mainly for running so this will be nice. I have a smaller head and this fitted well but after 1/2 hour or so it starts to feel a bit tight. I think I will get used to it. I didnt like the flashing blue lights but you can turn it off. It would have been nicer with a small led instead. The music did cut out sometimes but repairing fixed it.
