Plantronics Blackwire C720-M Headset
There's a lot to like about this headset, though it lacks a few features as well. This computer headset has a great, fully adjustable noise-cancelling microphone and excellent speakers built into the ear cups. The inline controls on this model are nice with up and down buttons for volume and a mute button. While the volume buttons work, a volume wheel is usually more precise than "up" and "down" buttons. However, like other headset models these controls do add weight to the cord.
One of the best things about this computer headset is it works through both a USB connection and Bluetooth. You can have it physically connected to a PC and paired with a mobile phone through Bluetooth, and easily swap between the two devices. The headset is quite lightweight, folds up for flat storage, and includes sensors so the headset automatically answer calls when you put it on.
