Knowing your needs beforehand can help you narrow your search. The spectrum of USB headsets on the market is wide, and at the end of the day most models are designed for one specific task. Are you a gamer looking for crisp and immersive sound and a high-quality microphone? Or maybe you work in a busy office and need a headset that can offer clear audio as it blocks out background noise. When shopping for a USB headset, consider how you will use it.
Not all headsets have a boom that can rotate to be used on either side.
Just as most people have a preference for a side when talking on the phone, you may have a preference for the position of your microphone.
