I have never had a portable mp3 player so I cannot compare sound quality of these devices so how does it compare to other iPods or portable media players. I have just bought a shuffle and I am not that happy with the sound quality. The sound is flat, with very little separation or have I just been spoilt with my other top end gear. I am using the standard earphones and using the default 128 kbps compression. I have ordered Koss KSC-75 headphones which hopefully improve the sound. Does anybody know what the law is on returning electronic goods that have been opened (Curry's) as I would like to replace it with a better quality player?
