Dubbed the Molar Mic, it's a small device that clips to your back teeth. The device is both microphone and "speaker," allowing the wearer to transmit without any conspicuous external microphone and receive with no visible headset or earpiece. Incoming sound is transmitted through the wearer's bone matter in the jaw and skull to the auditory nerves; outgoing sound is sent to a radio transmitter on the neck, and sent to another radio unit that can be concealed on the operator. From there, the signal can be sent anywhere.
The Molar Mic connects to its transmitter via near-field magnetic induction. It's similar to Bluetooth, encryptable, but more difficult to detect and able to pass through water.
Sonitus received early funding from In-Q-Tel, the nonprofit investment arm of the CIA, to develop the concept. Hadrovic declined to say whether CIA operatives had used the device in intelligence gathering. But the Molar Mic has seen the dust of Afghanistan and even played a role in rescue operations in the United States.

This does look like interesting tech, both using your bone structure to couple sound, and using PSK instead of ASK seems like a sensible improvement over NFC (because someone realised the use case isn't "put as-cheap-as-possible RFID chips on everything" anymore).
Too bad about the marketmangling speak in the article.
Some red flags:
If the transmitter is in your mouth and you're wearing the receiver, all you care about is "able to pass through human tissue".
Only if that distance is 10cm.
And if the range is "Up to 3m", why do you need to wear a repeater around your neck?
No one remembers the singer.
