COOSPO HW9 Heart Rate Monitor 5.0 ⌚
Description:
This optical armband heart rate monitor measures pulse and calorie burn during workouts, offering a more comfortable alternative to chest straps while allowing freedom of movement for cycling, running and gym sessions. With an LED heart rate zone indicator and support for HRV, it helps you keep training intensity visible at a glance and manage effort during interval work and steady-state sessions.
Key Points
The armband uses optical sensors that the manufacturer states achieve an accuracy of ±1 BPM, which aims to deliver reliable heart rate and calorie data for training. It connects over ANT+ and Bluetooth 5.0, allowing pairing with bike computers, fitness apps and smart watches, and it supports two simultaneous Bluetooth connections for paired devices. A vibration alert notifies you when your heart rate exceeds a set maximum, and you can customise that limit through the companion app.

Usage Recommendations
Wear the armband on the upper forearm following the app guidance to improve contact and signal stability. The soft, breathable and adjustable strap is intended to reduce movement during exercise, which helps when using the monitor for high-intensity intervals or cycling workouts. For pairing, enable ANT+ or Bluetooth in your chosen app or device and follow the on-screen prompts; using the latest app versions typically ensures the best compatibility with platforms such as Peloton, Strava and Zwift. ⚙️
Positive Aspects
The five-colour LED zone indicator provides immediate visual feedback during sessions, so intensity can be adjusted without looking at a screen. The HRV function adds another layer of insight for recovery and stress monitoring, according to the product details. Rechargeable operation with a magnetic charger and long battery life reduces interruptions during multi-day activities or extended rides. Consider that optical armbands can be affected by very loose fit or excessive movement, so correct positioning and strap tension are important for consistent readings. 🏃♀️📈
