that was me above that asked the question I forgot to log in,
thanks for the reply on teh N1 sound output. I'm more interested in Sony models for the US because I can always get the warranty for it which is important to me. So far the cheapest N1 i found is around 300~ USD where as N10 I can get it for $250 USD which I can spend towards a better earphones.
As for sharp i thought about it, but due to warranty issue and prices i'm not sure if they are worth the extra buck?
