Totally agree. I have a Medusa headset. Big and clunky, cheap cable and probably the worst shielded amp in existance. You can't put a mobile phone within 20 yards of it without hearing all the interference.

Go with someone who uses quality components like Senn or Bayer.

5.1 headphones are nowhere near as good as a proper 5.1 speaker setup. If I was buying again I'd prob go for a lightwieght simple stereo headset made by someone decent.

Check out multiple reviews before you buy.
