Hey guys, would you recomend me a really REALLY good MP3? I use an Ath m50. 

Hi everyone, I'm looking for a new mp3 player. I have a cowon i9, sounds good but not "amazing" sound... Would you recommend me a new one? Dont care about price.

Use for Rock(especially), metal, rock pop, classic, jazz, acoustic, etc.   Wich is the best?

How about Sennheiser hd 25-1 II ?

So, shure are better? Sorry, i dont understand english as well.

Wich headphone sound very nice with my cowon i9?   I hear shure h840 are a little uncomfortable. Is that true?

Hey everyone! I'm new here and I'm from Perú so my english could be a little bit poor, sorry!, whatever... I think to buy a M50 because some reviews just say wonderful things about this cans. I hear Rock, Hard rock, metal, pop, salsa, ballad, etc. Do you recommend me this headphones? And is...
