Shokz OpenSwim Pro USB-C Grey Bone Conduction Headphones

Shokz OpenSwim Pro: Waterproof Bone Conduction Headphones with Bluetooth and 32GB MP3 Storage

The Shokz OpenSwim Pro USB-C 32GB Grey is a waterproof bone conduction headphone engineered for swimmers, triathletes, and outdoor runners who refuse to leave their music behind when they hit the water. This model combines Bluetooth 5.4 streaming on land with 32GB of built-in MP3 storage for cable-free laps, all wrapped in an IP68-rated housing that survives submersion down to 2 meters. Athletes looking for a headset that handles the pool, the bike, and the trail can count on it to perform without skipping a beat.

What Makes the OpenSwim Pro Stand Out

Most swimming headphones force a compromise between Bluetooth convenience and underwater reliability. Dual-mode operation lets you stream via Bluetooth 5.4 for everyday listening and switch to the 32GB MP3 player whenever water disrupts the wireless signal. PremiumPitch 2.0+ bone conduction technology, along with a dedicated Swimming EQ Mode, keeps vocals and bass clear even with swimming earplugs in place.

Waterproof Construction and Safety Features

For swimmers and open-water athletes, an IP68 rating is the difference between a headset that survives a season and one that fails after a few sessions. The triple-sealed chassis and breathable microphone membrane keep sweat, splashes, and full submersion from interrupting playback.

• Waterproof Rating: IP68 — submersible to 2 m for up to 2 hours, with a triple-sealed body and breathable mic membrane.
• Bone conduction transducers sit on the cheekbones, leaving the ear canal clear for ambient sound and earplug use.
• Materials: Silicone, plastic, nickel-titanium alloy headband — flexible ear hooks hold the frame steady through flip turns and wipeouts.

Audio Performance and Frequency Response

Bone conduction has a reputation for thin sound, so Shokz tuned the OpenSwim Pro USB-C 32GB Grey around its 8th-generation platform with PremiumPitch 2.0+ to add body without sacrificing clarity. The full-range frequency response covers everything from sub-bass kick drums to vocal sibilance, and the Swimming EQ Mode rebalances the curve for underwater listening.

• Frequency Range: 20 Hz – 20 kHz — full-spectrum response that handles music, podcasts, and audiobooks.
• Speaker Sensitivity: 105 ± 3 dB — enough headroom to cut through pool noise and outdoor traffic.
• ENC and DNS dual noise reduction combine with a -38 ± 1 dB microphone sensitivity to keep calls clear between sets.

Battery Life and Connectivity

Long training blocks demand a headset that outlasts the workout, not one that dies mid-lap. The OpenSwim Pro stretches to 9 hours in Bluetooth mode and 6 hours in MP3 mode, with a quick-charge feature that rescues forgotten charging sessions.

• Play Time: 9 hours (Bluetooth) / 6 hours (MP3) — covers full Ironman-length sessions and multi-day race weeks.
• Quick Charge: 10 minutes for ~3 hours of playback via the included 4-pin magnetic cable.
• Bluetooth Version: 5.4 with Multipoint Pairing — connects two devices at once, including smartwatches, phones, and tablets.
• Wireless Range: 10 m — stable streaming across a gym floor or open-water deck.

Who Benefits from the OpenSwim Pro

Triathletes, open-water swimmers, and multisport runners all find a solution in this model, moving from pool to pavement without changing gear. Lane swimmers make use of the 32GB MP3 library and included earplugs, which block water and keep audio clear. Trail runners, cyclists, and gym-goers stay aware thanks to the open-ear design, while Bluetooth 5.4 and multipoint pairing support modern devices. Those who rely on top-tier voice call quality should consider supplementing with an office-dedicated headset.

Shokz Story and Product Background

Shokz earned its reputation for open-ear bone conduction technology designed to keep athletes aware, and the OpenSwim Pro USB-C 32GB Grey brings that vision underwater. Endorsed by athletes like Olympic and Ironman World Champion Jan Frodeno and UTMB Mont-Blanc champion Tom Evans, the headset is credited for delivering music during long swim sessions. Launched in June 2024, this instrument is the first swim-ready model from Shokz to offer both Bluetooth streaming and MP3 playback, replacing the older 4GB OpenSwim with a 32GB successor featuring longer battery life and multipoint connectivity.
