In reply to zigzag:
I moved over to using large studio-can type headphones a while ago as the little in-ear buds just don't do it for me anymore.
These are an absolute minefield, as you can spend loads of money on terrible sounding 'phones that don't deliver. Best thing to do is go to a shop that has a load plugged that you can try - I recall John Lewis doing that in their tech section. Make sure you listen to the genre of music that you will enjoy - i.e. jazz requires a different set tones than hip hop etc. Try listening to some Miles Davis on some Beats headphones and you will see what I mean.
Unless of course you are listening to it out of the built in speakers..
