I just bought a used pair of AKG K240 headphones, and it's my first "expensive" set of headphones.
When nothing is playing, I get really quiet and subtle staticky noise. It doesn't bother me, but is it normal?
Also, a big problem is that whenever I play something with a piano in it, if the piano is playing any non-bass notes somewhat loudly, there is very noticeable static. It seems to only happen with pianos. Is that something fixable?
My headphones are connected through a set of cheap speakers. Do those speakers make any difference, or will it sound better if I just connect it directly to my computer? If I do, is there any way to increase the volume (since there's no knob on the headphones)?
My old cheap pair of headphones had similar problems. Maybe it's the computer? Also, what I find odd is that when I do something like move the mouse, the ambient static changes a little. So if I move my scroll wheel, the static becomes a little different, and when I flick my cursor around, it changes too. Is this normal?
Are my headphones just messed up or is it something that has to do with my computer itself?
Thanks for your help guys.
