Open-ear sport headphones with Sony's legendary audio quality
Visit Sony →The Sony Float Run brings Sony's decades of audio engineering expertise to the open-ear sport headphone category, delivering what may be the best-sounding open-ear workout headphones available. Unlike earbud-style open-ear designs, the Float Run uses a neckband format with two off-ear speakers that sit just in front of your ear canals, directing sound into your ears without blocking them. This design provides excellent situational awareness for running and cycling while delivering surprisingly rich and balanced sound — a Sony specialty. With IPX4 water resistance, up to 10 hours of battery life, and Sony's signature attention to audio detail, the Float Run is ideal for runners who value both sound quality and situational awareness. The neckband design is lightweight and comfortable, and the headphones stay securely in place during vigorous activity.

Sony Float Run uses conventional speaker drivers that sit just in front of your ear canals, whereas bone conduction vibrates your cheekbone to transmit sound through bone. Both keep your ears open, but the Float Run generally delivers better sound quality — richer bass and more detail — because it uses traditional air conduction. Bone conduction can be more comfortable for some people and works better underwater, but the Sony wins on sound quality.
Yes, the Sony Float Run is excellent for long-distance running. The open-ear design keeps you aware of your surroundings, the neckband is comfortable for hours, and the 10-hour battery life is enough for even marathon training runs. The sound quality is also better than most open-ear options, which makes long runs more enjoyable.
No, the Sony Float Run only has an IPX4 rating, which means it's sweat and splash resistant but not waterproof. It will handle heavy sweat and being caught in rain, but it shouldn't be submerged. If you want headphones for swimming, look for bone conduction options like Shokz OpenSwim or the JBL Endurance Peak 3.
Surprisingly good! Sony's audio engineers have done impressive work with the Float Run. While it can't match the deep bass of sealed in-ear earbuds, the bass is tighter and more impactful than other open-ear designs we've tested. It's not bass-head level, but there's enough low end to make pop, hip-hop, and EDM enjoyable for workouts.
The Sony Float Run is the best-sounding open-ear sport headphone we've tested, delivering Sony's legendary audio quality in a workout-friendly design. The neckband format is comfortable and convenient, and the situational awareness is excellent for outdoor running. While the IPX4 rating and battery life are just average, the sound quality sets it apart from competitors. If you're a runner who values both safety (awareness) and great sound, the Float Run is worth considering.
