Hi, I've just got some etymotic 6i earphones to go with my much-loved md player. However, using them with my minidisk player they sound very loud - I have the minidisk on the lower possible volume setting in order to get a moderate listening level. More annoying is that they hiss - they're silent when nothing's playing, or when the MD player is switching between tracks, but a hiss starts when a track starts playing. Any suggestions as to why this might be :Not Sure: or, better, what I could do about it Earphones are fine from my laptop, and another pair of headphones work fine on the md (no hiss). Thanks in advance, Jon
