Key Benefits
- Delivers precise heart rate readings.
- Comfortable alternative to chest straps.
- Tracks up to three devices at once.
- Long battery life for uninterrupted use.
- Automatic power-on with wear detection.
The COROS Heart Rate Monitor offers a comfortable, arm-based alternative to traditional chest straps—without sacrificing accuracy. Using an advanced multi-channel optical sensor, it delivers high-quality heart rate data you can trust during training or everyday movement. The soft, textured band sits snug against your arm, staying secure during intense sessions without slipping or chafing.
It connects effortlessly to up to three Bluetooth-enabled devices at once, including smartwatches, indoor trainers, and bike computers. With automatic wear detection, the monitor powers on when worn and syncs with your paired devices—no buttons needed. The low-profile design stays out of the way, letting you focus on your workout, not your kit.
You’ll get up to 38 hours of use on a single charge, or up to 80 days in standby mode. The sensor detaches easily from the band for quick cleaning, while a magnetic USB cable keeps recharging simple.
Designed with accuracy in mind and comfort at its core, the COROS Heart Rate Monitor helps support a more consistent, data-informed approach to movement—wherever you are in your wellbeing journey.

The best wellbeing website…
The best health and wellbeing website in the UK. The range of products is fantastic, even on hard to reach USA products. I love the subscription service too. I'd be lost without this website.

Amazing!
Healf isn't just another wellbeing brand. They really get it. The products are fantastic, and the support is always so personal and genuine!
Janet
Great products, service, and customer support
Healf have a great range of wellbeing products not available elsewhere in the UK. They are competitively priced as one-off, but even better if you take up the 'subscription' which is super flexible too. I'd have no hesitation in recommending Healf.

I love Healf
It's the only place I get really decent health and wellbeing brands, particularly US brands. I've bought a Pvolve set, lots of Skinny Confidential stuff, Thorne supplements etc., the really great stuff that's impossible to get otherwise.
