Good microphone/headphones, but WILL NOT work with a laptop or computer plugged into a non-grounded outlet (produces a buzzing noise in the background).

After some troubleshooting, the buzzing noise appeared to occur when ever the cable to the headset was touching any other cable (e.g. power cord or itself)

These made an awful buzzing noise

At first, these were working great, but then I started to hear a buzzing noise

They lasted forever and felt great, when they finally broke I bough them again
