I've recommended these before, but if anyone's interested in some very reasonably priced earphones for a mobile device then you cannot beat these:
Panasonic RPTCM125EK Headphone with Microphone - Black " onclick="window.open(this.href);return false;
They cost just over a tenner and the sound is fantastic with incredible base. Many professional reviewers rate them as being on par with far more expensive alternatives. I'm actually using the upgraded version currently after losing my 125's (TCM165 iirc), they cost me £25 but the sound isn't as good!
