Suunto Spark: Open-Ear Audio for Trailblazers

The Suunto Spark earbuds feature an open-ear design, perfect for runners, bikers, and hikers who value situational awareness. Weighing just 9 grams each, their titanium and silicone construction provides a secure yet comfortable fit, even with accessories like glasses.

These earbuds boast an IP55 rating for sweat and rain resistance. Control is managed via touch panels, which allow for track skipping, play/pause, and volume adjustment, though accidental triggers are possible. Head gesture controls for calls and track skipping are less reliable, especially during strenuous activity.

Audio quality is a standout feature, comparable to leading brands like Shokz and Bose. The earbuds offer extensive sound customization through the Suunto app, including four EQ presets and a custom option, along with a spatial audio mode for immersive listening.

The Suunto app also enables workout tracking, providing metrics like cadence and vertical oscillation, though these may not always align perfectly with dedicated devices. A metronome feature is available to help maintain running tempo. Cyclists can benefit from posture alerts and neck mobility assessments.

Battery life is rated at seven hours on a single charge, with the compact case providing an additional 29 hours. A 10-minute charge yields two hours of playback. With a premium price of $179, the Suunto Spark earbuds justify their cost for those prioritizing excellent fit and sound with added athletic features.
