I think the Motorola ROKR S9 headphones are lovely and they are comfortable to wear for a long time. the battery life is good and my phone usually runs out of battery before the headphones. The headphones have very good sound quality and the are much better than i expected them to be. I would recommend buying these if you are looking for headphones. I would look elsewhere if you need them for phone calls mostly.

I first bought these headphones for my Motorola Razr V3i (iTunes) but weren't compatible as the bluetooth in your mobile has to have A2DP technology and so the headset only worked as a device to receive calls. So I then had to wait until I got my new mobile which was compatible.

The sound quality is very good and clear which for music lovers is very important.

However there are a few bad points. I think the main problem is it's looks, it looks fantastic but once you put them on you look like a dork, i for one wouldn't walk around town wearing them.
Another bad thing is that the behind the head design makes it hard to wear when sitting down. I usually use them in my car and when i want to rest my head back i can't because of the fear of breaking them.

The battery life is very good but if you do happen to run out of battery in a busy place the music will continue to play through your mobiles speaker which isn't very lucky if you happen to be listening to something rather like to keep private such as "Puppy Love" :P

What i find most annoying is receiving an incoming call, the headset plays your ring tone full blast therefore deafening you or scaring you half to death.

Overall these are a reasonably good set of headphones. I advise that if you are considering buying them you should check that your mobile is A2DP compatible.
