headset

Problem: I've heard from a lot of people about hum or background 'buzz' in recordings and Skype conversations when using a USB headset (like the one I have, the Logitech USB Headset H350). Almost every time I hear someone having this trouble, they're having the problem while using the headset with a laptop.

Solution: about 99% of the time, the problem is fixed by simply plugging the laptop into a grounded (3-prong) outlet.
