one simple “best” way is to buy the most expensive pair of headphones not ‘earphones’, which has the impedance around ~50 Ohms !!! this type of headphones fits on any portable audio device (iPod, Any cell-phone,laptop soundcard ) and offers impressive sound-quality .

any headphone with a higher impedance needs a headphone amplifier and that means more money .

good headphones brands are Grado, Sennheiser , AKG . else you may buy the rest …….

if you love sounds clean sharp warm sounds, if you are a little “audiophile”, if sounds are giving you moods then use winamp or windows media player with the adaptX plugin add some of these , get yourself a very very good soundcard , an amplifier  and  2 speakers from here or from here or here , or maybe here and you will have impressive results .  else go for this .

choice of the right speakers is a problem so read some articles from here . hope it helps.
