I bought these right when 3.0 for the iPhone came out and got a fantastic deal on them and i couldn't be happier. Battery life is amazing, i charge it it seems like once a month and i use it on my phone listening to music, on the playstation playing call of duty and for work taking phone calls. You sort of get use to the discomfort after a while, they aren't the most comfortable things in the world but they aren't unusable either. Sound quality was way above what i expected for wireless music. Just all around great headphones.
