Lightweight open-ear headphones delivering superior sound and all-day comfort. Designed for training and everyday activities.

Open-ear sports headphones designed for movement. Suunto Spark delivers powerful bass and crisp highs, with an open-ear fit that keeps you aware of your surroundings. Light and comfortable, Suunto Spark stays securely in place through every run, ride and workout, helping you stay focused and energised.

Suunto Spark supports LHDC 5.0 for ultra-clear, high-fidelity audio up to 96 kHz, with deep bass and finer detail. The hybrid multi-driver open-ear system produces powerful, balanced sound. Enjoy immersive spatial audio with head tracking and fine-tune your listening with preset EQ modes, or create one of your own.

Use the Suunto app to set your cadence from 120 to 200 steps/min and improve your running efficiency. Turn on Sport mode to track cadence, ground contact and vertical oscillation in real time. Get voice updates on pace, heart rate, distance and laps from your Suunto watch. Complete the neck mobility assessment to monitor flexibility and range of motion.

Weighing under 10 g each and finished in soft, skin-friendly silicone, the earbuds rest lightly on your ears for lasting, all-day comfort. The slim silicone-coated memory titanium ear hook follows the shape of your ear and locks the fit in place as you move, so you can stay focused on the moment.

Dual microphones with environmental noise cancellation reduce background noise and improve voice clarity in noisy surroundings. Suunto Spark’s anti-leakage driver uses active sound control to minimise sound leakage and keep your listening more private.

It offers stable, low-latency connections to keep games, calls and music in sync. Connect two devices at once and switch between calls, music or video without missing a beat. Use the Suunto app to find lost earbuds, check their status, customise EQ settings and adjust features.
