The Denon AH-C820W wireless in-ear headphones bring the neckband style of earphone into the Denon range. This style is one that I personally get on very well with. I've got several choices for work-related voice communications, and tend to reach most frequently for the Plantronics Voyager 6200 UC: I find the combination of wireless, in-ear comfort, round-the-neck security and easy access controls is a winner for me.
