There's no way you'd want to listen to an album this way even if it were possible, but the system is theoretically clear enough to keep conversations intelligible. We're told the Sgnl can store up to five contacts, which you can sift through using a set of slightly-too-gummy navigation buttons.

The Sgnl also doubles as a fitness tracker because, well, why not? Good thing it's relatively comfortable to wear. The prototype units I've tried in the past were considerably more bulbous and hack-y, but the final product is actually remarkable restrained in its design. The actual body conduction bits are housed in a soft-touch plastic body, while a dark stainless steel strap runs around the rest of the wrist. My biggest concern so far, though, is how clumsy the clasp seems; you have to stick the tiny metal tab on one end into the slot on the other, and it can be difficult to do with just one hand.

Even now, with Sgnl production in full swing, the wearable leaves some unanswered questions. Thankfully, we won't have to wait too long for clarification: The first units will be delivered to Kickstarter backers in March, with wider availability to follow soon after.
