The Sgnl is a watch strap that transmits the sound of a voice call through your finger when you press it against your ear.
It transmits the sound to your ear with vibrations from the Sgnl's "body conduction unit." It also features an audio algorithm that "selectively amplifies voice signals," and it picks up your voice with a built-in microphone.
The "body conduction unit" is found on the underside of the Sgnl strap. Sgnl claims the unit doesn't use up much power and that it should last up to four hours of voice calling. You charge it via a microUSB cable.
It also has buttons to control volume, and a switch for Do Not Disturb mode.

For voice calls, the Sgnl strap connects to your smartphone via Bluetooth, just like you would with any Bluetooth headset.
There's also a Sgnl app that lets you choose what notifications you want to receive, like emails, messages, or calendar events.
The Sgnl also acts as a fitness tracker with the Sgnl app.
You can add the Sgnl strap to a regular watch, a smartwatch, or you can use it on its own.
