I recently purchased a HM-602 from a member. When I first used my M50s with the player, there was no background noise, but when I used my TF10x6 there is an audible hissing noise coming from the headphone. I've used that headphone with my iAudio x5, which makes me suspect that something is up with the DAP. What I want to know is if this phenomenol is normal or not?

I never noticed a hiss with my iems and the 602 when I briefly owned it.

However, try asking in the portable source forum - someone there might have had a similar experience
