This is the Star Trek TNG Bluetooth ComBadge available exclusively from ThinkGeek this November for $80. The Bluetooth badge has an internal microphone and allows users to answer and end calls with a push of the insignia. Oh, plus it makes the combadge chirp sound whenever you press it.
Once connected, one touch answers/ends calls, plays/pauses audio, or accesses Siri, Google Now, or Cortana. And, of course, a touch plays that classic communicator sound effect. Warning: you're going to want to keep the micro-USB charging cable handy right after you receive this, because making it chirp is well-nigh irresistible.
Man, I can't wait for a coworker to get one of these and have it chirping all day long. I guarantee it'll be one of those things that I think is kinda cool at first, but get old really quick until one day, and possibly just later that same day, I look in my rearview mirror and realize I'm driving away from a burning office building.
Keep going for one more shot.
Thanks to Andrea, who agrees you should be able to mod the badge to play any sound when you press it, like the theme from Golden Girls.
