Suunto Spark Review: The Perfect Pair for Runs and Rides

You may not have heard of the brand, but Suunto is no stranger to audio. Despite having started as a navigation company, the Suunto Spark is its fifth audio launch in just under five years. This time around, the Suunto Spark adopts the newer open-ear form factor in place of bone conduction, which turns out to be a perfect fit for runners, bikers, and hikers. These are earbuds made for people who will gladly swap pavement for trails and could be lured by the prospect that what’s on your ears could replace what’s tracking your movements on your wrist or in your pocket. The Suunto Spark open earbuds have quickly become my favorite pair of buds to work out with. Hanging Right When it comes to earbuds, fit is everything. That's even more important for those designed for runs or long weekend rides. The first thing Suunto gets right is the weight. Each earbud weighs 0.3 ounces (9 grams), so while they’re not the lightest earbuds available, the mix of titanium and silicone is distributed well from the speaker unit to the flexible ear hook. I’d describe the fit as reassuring without ever feeling like they’re clamped to the outside of your ear. I wore them with caps, regular glasses, and sunglasses, and those added accessories didn’t see the Spark struggling to compete for space.
