My Shure SE-420s are 22ohms... If I listen very carefuly, I hear a low hiss on my 829...but I doesn't disturb me as it is pretty low level. I think all Sony DAPs hiss a bit. I lose it all when the music starts, that's what counts!
But I really don't know how it relates with earphone impedence. I'd be curious to know though!
Thanks for your insight balis65! Your observations echo what I've previously encountered but what concerns me is ur shures have a much lower impedance than my SA6's and from what I've come across the higher the impedance of a headphone the greater the hiss generated/percieved/detected. I imagine I could deal with what you depict just fine as it sounds no more detracting than low-mild microphonics, its that I could experience a more obvious and powerful hiss that bothers me, something you cant get away from and what tarnishes your listening experience. Thanks for sharing your experience and also expressing interest in undrstanding electrical impedance (in relation to dap-headphones) tho.
Any more insights anyone?
