The Dash in-ear headphones are about to change your daily run or gym trip. That’s because, not only do they pump music into your ear holes like any ole pair of headphones, but they also monitor your heart rate, oxygen saturation, and energy spent. Through tracking your pace, steps, cadence, and distance, they provide you with real-time acoustic feedback on how your workout is going. With a built-in microphone, they also can act as a headset as long as you promise not to be the guy on the treadmill having a conference call. They also have 4GB of storage and their own audio player so you can listen to music even if you’re not near your phone. All in all, they’re pretty damn impressive.
