Yep, they are awsome headphones, but are only supposed to be used with SE phones, if you plug them into anything else, the sound is not as good - that's my experience of them.

One of its downsides is that if you wear glasses, it is a very tight fit and u will end up having to either take ur glasses off or the headphones :P

These really are a fantastic pair of headphones. The sound is so much better than anything i have heard. They are definatly better than the ones that come in the box with the Sony Ericsson W850i. There is only one downside and that is the length of cable that attaches to the headset from the remote. You really can't use this product with any other mp3 player etc as the 3.5mm headphone cable reaches your shirt pocket when you are wearing it. Regardless if you have a Sony Ericsson you have to buy these headphones they are just awesome
