With analog headsets, there are some other ways of fixing the problem by isolating the signal better. With USB headsets, the only way to fix this is to plug your laptop into a grounded outlet. This is a surefire sign you have a ground loop problem. Sometimes, if your laptop or a USB accessory is made of metal, you might notice the buzz goes away if you touch a metal part. When you plug in your laptop to a grounded outlet (3 prongs), the circuits for audio in the laptop have a 'ground' signal to make sure the audio doesn't get any interference. The problem is caused by a well-known phenomena, a ground loop. On a PC, different adapters work differently, but hopefully you have a power adapter with a 3-prong plug. On a Mac, if you're using the Apple power adapter without the extra power cable (with a 3-prong plug instead of the 2-prong plug), you may get a buzzing sound. Solution: about 99% of the time, the problem is fixed by simply plugging the laptop into a grounded (3-prong) outlet.
I have a headset that i need for a mac but has a usb software#
Also check with the manufacturer of your USB device for firmware or other software updates. Your device might need more power than the port it's plugged into can provide. If your USB device came with an AC power adapter, you should probably use it. Almost every time I hear someone having this trouble, they're having the problem while using the headset with a laptop. Plug your device directly into your Mac instead of a USB hub or other device.
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).
