Performance In Every Beat
Suunto Spark are open-ear earbuds designed for training and everyday activity, delivering immersive audio without compromising awareness. Using air-conduction technology, Spark allows you to enjoy music, calls, and podcasts while staying alert to traffic, people, and your surroundings — helping you move safely and confidently. Lightweight and secure, each earbud weighs just 9 grams and features a flexible memory-titanium loop with soft silicone for a comfortable, pressure-free fit that stays in place during runs, workouts, and daily wear. Built for performance, Spark is IP55-rated for dust and sweat resistance and offers up to 8 hours of battery life, extended to 40 hours with the charging case. More than just headphones, Spark also acts as a training companion. Integrated insights help monitor cadence, running mechanics, and neck posture, while voice guidance delivers real-time updates when paired with a Suunto watch — keeping your training focused and hands-free. From busy commutes to long runs and outdoor adventures, Suunto Spark delivers a smarter, safer, and more connected listening experience.
