The communicator K309 are designed to sit around the back of your neck and loosely fit on your ears. It’s a good idea and one that means you don’t have to wear an intrusive alice band design and mess up your hair in the process.

With the design, however, comes a host of other problems; mainly that you can’t sit down and lean back on a headrest without it being uncomfortable.
