I have these as they came with my sony ericsson phone. The sound quality is excellent as my phone has an mp3 player inside it. The picture is actually misleading, as you have to buy a converter to put the headphones into your phone, so thats an extra 5pounds, as most sony ericsson phones have a different plugin type that just the standard headphone one. You can buy these headphone and converter as I did in 3mobile shop for 30 pounds. They are really worth the money as they are just as good as listening to an ipod, and you dont have to carry round a seperate mp3 player if you already have one in your phone. The only bad thing is that theres no answer call button on the lead of the headphones, which would be useful if someone rings and you are listening to music that I have seen on other models.
