;8427541']i use my w810 headphones on my n73 me and my old w810... i perfer the walkman app, its much more polished then the n73, although nokia has improved their mp3 player over their previous s60 phones that use realplayer...
music playback on the nokia is really good, in fact i dont notice much difference compared to the w810, it really depends on what headphones you use... what the n73 does better is playback through its speakers, there are speakers on the top and bottom of the phone, volume is very loud, and it gives off a stereo effect as well, if you've used the w600i from SE, its even better then that with the stereo widening feature
its important for me because i work in a somewhat noisy environment and im not allowed to wear headphones, i am able to blare music out of my phone in my pocket, and can still hear music over machine noise... =D
