Suunto Spark Review: The Perfect Pair for Runs and Rides

For anyone who thrives on the challenge of trail running or the rhythm of a long bike ride, the Suunto Spark earbuds are a game-changer. Designed with the needs of outdoor enthusiasts in mind, these earbuds are more than just a way to listen to music — they're a reliable companion that offers sound and fitness tracking that keep up with the pace of your activity. Their open-ear design and advanced features make them a standout choice for those who need both audio and data during their workouts.

Fit That Stands the Test

Fit is the cornerstone of any sports earbud, and the Suunto Spark excels in this department. Weighing in at just 0.3 ounces per earbud, the design uses a combination of titanium and silicone to distribute weight evenly across the ear and the flexible ear hook. This balance ensures the earbuds remain secure during high-impact activities without feeling intrusive. Whether worn with glasses, sunglasses, or caps, they maintain their position without clamping down on the ear, which is a common issue with many open-ear models. The secure fit is especially crucial during intense runs or rides, where loose earbuds can be a distraction or even a safety hazard.

The Suunto Spark is rated IP55 for sweat and rain resistance, which is essential for outdoor sports. However, the charging case lacks the same protection. The case is compact and easy to carry, fitting comfortably in a running belt or pocket. Despite the absence of a waterproof case, the earbuds themselves are built to handle the elements, ensuring they can keep up with the user through trail runs or bike rides.

Sound That Keeps Up With You

The Suunto Spark stands out in the crowded open-ear market with its impressive sound quality. Unlike traditional bone-conducting earbuds, the Spark uses air conduction, which places the speakers closer to the ear and mimics the experience of standard earbuds. This design allows for greater sound customization and a more immersive listening experience. Whether you're catching up on a podcast or fueling your run with high-energy music, the Spark delivers clear and balanced audio that adapts to your needs.

The Suunto app offers four EQ presets and a custom option, enabling users to tailor the audio to their preferences. The spatial audio mode, when paired with the most balanced EQ setting, delivers a bright and energetic sound profile without overwhelming bass. This makes the Spark ideal for everything from podcasts to high-energy playlists during a workout.

  • The spatial audio mode enhances immersion.
  • EQ presets allow for sound customization.
  • Wind noise is effectively minimized.

Features for Cyclists and Runners

Beyond sound, the Suunto Spark is packed with features tailored to cyclists and runners. The neck fatigue alert and neck mobility assessment are particularly useful for cyclists, reminding them to maintain proper posture and check their neck muscle health. These features are designed to help users avoid injury and optimize their performance, making the Spark more than just an audio device.

However, one notable absence is the LED lighting feature found in Suunto’s Wing series, which could have been beneficial for low-light cycling conditions. While the Spark offers excellent tracking and audio features, the lack of LED lights might be a drawback for riders who frequently train in the dark.

Battery life is another key consideration. A full charge provides up to seven hours of playback, with an additional 29 hours in the case. The battery drain depends on the EQ settings and volume levels. While the battery performance is solid, it doesn’t surpass the best in the market, especially when using advanced audio modes.

A Verdict for the Outdoors

The Suunto Spark represents a significant step in Suunto’s foray into the audio market. At $179, they are a premium product, but the combination of secure fit, excellent sound, and integrated fitness tracking makes them a strong contender for outdoor enthusiasts. While there are minor drawbacks — such as the lack of LED lights and occasional gesture control issues — the overall experience is compelling.

As fitness and audio technology continue to merge, the Suunto Spark sets a new benchmark for open-ear earbuds designed for movement. Whether you're lacing up for a run or adjusting your bike position, these earbuds are engineered to keep up — and possibly even improve — your performance.
