My only gripes about this headset is that the muffs (I actually don't know what they're called) are a bit big. They're made of thin foams that's why I wouldn't recommend wearing them for long hours, unless you want your ears to hurt. It's hard to adjust the microphone because it is a bit flimsy and quite long. The audio quality is good as long as you're 30 feet near your source. It is not shipped with adapters so you need to buy one to connect it to a Bluetooth phone.
