Wireless earphones are kind of cool. Wireless earphones that track your pace, heart rate, steps, cadence, and oxygen saturation, and act as a bluetooth headset for phone calls—well, that’s a lot of cool. Imagine going on a run and listening to music without getting tangled up in cords. Now, take that scenario a step further: Imagine doing that while gauging nearly every aspect of your fitness along the way. After a hugely successful Kickstarter campaign (parent company Bragi raised nearly $3.4 million), The Dash Smart Earphones are now in production and can be pre-ordered for $299 a pair. Since we haven’t been able to test them first-hand, the sound quality is yet to be determined, but more expensive headphones already on the market don’t have near the geek-power that Dash brings to the table. That’s got to count for something.
