Track your heart rate with the built-in monitor. A sensor in the earbud tracks your heartbeat with precision. You'll know when to push it and when to rest. Compatible with open fitness-tracking apps such as Strava and Runkeeper and the Philips Headphones app.

Run faster. Jump higher. Kick harder. You get clear sound, punchy bass and 6 hours of play time—even when monitoring your heart rate. A single charge takes 2 hours via USB-C and a speedy 15 minute charge gives you another hour of play time.

Go with the flexible wing tips made from silicone that fit securely under the ridge of your ear. Or opt for the ear hooks that fit comfortably over your ear. A choice of ear-tip covers let you create the perfect in-ear seal.
