start with the "best" pair of earphone (don't know which one, hehe), but it will go a long way if you don't already have one of those. Also mp3 might not be the best format to use. So try FLAC, AAC, WMA-lossless, WAV, etc. So besure the next player have those formats supported.
i realize that 'best' is subjective, however i imagine that some mp3 players have the reputation as having excellent SQ.
i'm only interested in listening to music with this player, not bothered with the video feature at all.
i'll be listening to pop and classic hard rock, and audiobooks.
i want it to have a lot of bass.
doesn't have to be big,4gb is fine.
presently i have the sansa clip+ and that sound ok. it is considered to have great SQ, but i'd like something better if possible.
