The Dash, a set of Wireless Smart In-Ear Headphones, pack so many sensors and features that it would take a pretty long article for us to cover them all. Consider this. There is a 3-axis accelerometer, a thermometer, a 5 field capacitive sensor, an ear bone mic, an ambient mic, and a red + IR LED & optical sensor crammed within two tiny buds that go inside your ear. Why? So you can “track your pace, steps, cadence, distance, heart rate, oxygen saturation, and energy spent, [while] relaying the information back to your devices via Bluetooth.” You can stream songs to them, or use the integrated 4GB of storage. You can block ambient sounds through passive sound isolation, or you can allow some sounds to filter in so you don’t get hit by a car. All these features are accessible via touch gestures on the outside of the buds themselves, by the way. The battery will last between 3 and 4 hours, which is pretty much the only blemish we see on an otherwise impressive package. And we’re just skimming the surface here. These buds have some serious tech in them, and for a $199 pledge, they seem to not be overpriced once bit.
