Built to stay out of the way.

The COROS Heart Rate Monitor delivers accurate, real-time heart rate tracking in a comfortable arm-based design. No slipping straps. No distractions. Just reliable data while you train.

Created in collaboration with Jakob Ingebrigtsen, it’s built for sessions where focus matters — from steady miles to hard intervals.

Precision that keeps up.

Using COROS’ latest multi-channel optical sensor, it delivers accurate heart rate monitoring across a wide range of training intensities.

Compatible with Bluetooth heart rate-enabled devices, it supports up to 3 simultaneous connections — making it easy to pair with watches, bikes, treadmills, and training apps.

Comfort without compromise.

Designed as an alternative to traditional chest straps, the soft adjustable band stays secure without restricting movement.

Wear detection automatically pairs the monitor with your device when training starts, while the removable sensor makes cleaning quick and simple.

Train longer. Charge less.

Up to 38 hours of continuous use or 80 days in standby mode on a single charge means less downtime between sessions.

Recharge using the included magnetic USB charging cable and stay ready for whatever’s next.
