I was very disappointed with this device. I thought it will be cool since it's awesome 15h talk time, but after testing it for just about a hour, I just had to return it. All seemed well at first - the device paired with my notebook seamlessly (probably because I don't have my XP infested with that horrible service pack 2..) and fit my ear perfectly.Unfortunately, when I played some music, listened radio and talked with my friends over skype, I discovered a MAJOR fault - the sound was fine, unless someone said anything with 's' - these consonatns sounds simply horrible, like white noise on your TV when you disconnect the anthena. It totaly spoiled the experience. Altough I haven't expected miracles (bluetooth bandwith is just about 700kbit/s afterall) I would expect headphone hardware to compress audio a bit more efficiently. This was MUCH worse than my good old undranded headphones I bought years ago in a thrift store. I do certainly expect more for stuff for $35 (originally $60) so I am going to return this. I wonder how much will they refund me..
