argh!!! i dont know why i never noticed this much before... perhaps because i never used it at night in house... or the koss previously relegated to the zen didnt reveal it...

but now i hear an audible screeching noise with the backlight off!

it is understandable if the noise is present when the light is on, because of interference (like my old V60t cellphone) but why the heck is it there all the time, but completely quiet when the background light is ON?!?!??!



-perplexed (and checking if toilet still flushes the correct direction)

it's a known issue.
i had it; and so have many others.
go to nomadness.net and go to
the zen forum and seach on 'background noise' or background hiss' and you'll find a lot of issues.
