HS70Se has static electric noice in the left ear cup

I've bought HS70SE headset two days ago and realised that they have the small static electric noise in the left ear cup. I thought that it might be some signal interference, but I've also tried with my laptop walking around the room, nothing helped. I've returned the pair to a shop and tried a different one. The problem was still the same. Since this problem is reported many times, I guess it is not fixable, so I am going to return this pair too and get my money back, unless there is a quick fix that I can try today.

When I have the headset connected but no sounds playing i hear a slight static in the left ear only. If i play a video or gameand pause it the static is quieter then a second or two later it gets louder and stays that way till i play the sounds/video again. I've tried different ports on the computer for the receiver. I've tried different computers all together. But its really bugging me and im not sure what to do.

 

I just bought on Amazon.com. I tried reinstalling firmware for headset.

When I plugged in the charger the sound comes more from the right side.

Headset's volume level does not affect static noise. Please help me...

Having the same problem here. I was hoping to replace my HS50 with the HS70 but the faint static is quite bothersome. I also ordered a replacement through Amazon and the replacement has the same issue. Quite the disappointment :(
