This might just be being picky after being spoilt using a dedicated music playing device like the iPod or Zune.
But it appears that whenever there is a gap between audio playing while using the headset you can clearly hear what I'd describe as white noise, like an old television set on a no signal channel for instance. It's very quiet but when I listen for it I can sadly hear during quiet music sections.
This was when using the provided headset. When I switched to a cheap(ish) creative in-ear set you could just hear it very faintly but otherwise unnoticeable.
Question is am I being picky and is this normal? Or is my phone and/or provided headset busted?
