Static in headphones - Sennheiser RS 120 Consumer Headphones

Adjust the tuning wheel on the side of the headphones so it picks it up.

Your cable or phone jack connection is defective.

you might check to make sure that your gain isnt to high many times this can negatively effect your sound quality

I found by spraying contact cleaner onto the switch and volume control the static went away on my MDR-IF5000 headphones

Don't try!!! instead get your mum to take them back and have them replaced or money back. By fixing them yourself you break the guarantee that comes with any new product.

these things are suppost to have a little static noise when on. next time get noise reduction headphones. they are like headphone style ear protection like what construction workers use. but only more stylish and they contain speakers. and no killing batteries for good sound. they are regular headphones but with really good sound isolation

well dumby all you got to do is get some new headphones, it's like 10$ stupid

check whether the sound comes when its unplugged.

Hello and Welcome to FixYa!
Yes Sir, as you have cross checked the audio so other possibilities have been ruled out, the only problem can be with your Head Phone unit, usually what happens is somewhere from inside the wire get cracked, or short resulting in noise or static, so the solution is to replace the wire, but the unit is a delicate thing so I'll never advice to D.I.Y.

I hope you have a clear picture now,
Regards, Waqar.

I get the same issue. I think its the headsets itself. I have no problem with any other headset but this one is just static.
