Wow. That’s one word to wrap up my impression of these in-ear headphones. Let’s cover the basics: The Dash is a pair of completely wireless stereo earphones. You can play music through a Bluetooth connection or use the embedded 4GB/1000 song music player. They can also keep track of distance traveled, steps taken, cadence, heart rate, oxygen saturation, etc. Want to talk on your phone through the headphones? Sure, they do that with an ear bone microphone. And, if you feel safer with a little ambient sound while you’re out running, you can choose to reduce the noise isolation with a quick swipe on capacitive touch surface.
