What is this? A separate boom microphone that plugs into the headphones' 3.5 mm jack. The other end goes to a computer or game console. An adapter is included for machines where the mic and headphones have separate jacks.
What do you get? A directional boom mic, a mute button and a volume wheel. The cable is about two metres. The Bluetooth delay disappears, which matters more to a gamer than style.
Why not just buy wired headphones? Because noise cancelling stays on, and you do not need a separate pair of headphones for the office or for gaming. The arm bends in front of your mouth. Stuck up your nose, it is of very little use.
Fits. VMK15, VMK19, VMK20, VMK25 and VMK25.2 headphones.
