NANK Runner Diver2 Pro Bone Conduction Swimming Headphones

Open-ear bone-conduction sports headphones with 32GB of onboard music storage, positioned for swimming and land-based workouts.

Our take: A considered option for swimmers who specifically need onboard music and prefer an open-ear fit. The water-focused feature set is appealing on paper, but buyers should accept the sound-isolation trade-off and verify comfort with their own swim and training equipment.

What works: 32GB onboard storage supports phone-free listening., Open-ear design can help maintain awareness during outdoor exercise., Listing specifies a swimming-oriented MP3 mode and waterproof construction., Adjustable ear hooks and included silicone strap are intended to support a secure sports fit.
Trade-offs: Open-ear bone conduction will not isolate outside noise like sealed earbuds., Swimming use relies on locally stored music rather than Bluetooth streaming., Fit with individual goggles, swim caps and helmets should be checked before purchase.

The NANK Runner Diver2 Pro is an open-ear bone-conduction headset designed for swimming, running and cycling. The listing combines Bluetooth 5.4 with a 32GB onboard music player, so it can be used without a phone for sessions where Bluetooth is impractical.

NANK advertises IP69 waterproofing, use at depths of up to 10m, adjustable ear hooks, a silicone retention strap and up to 10 hours of playback. It also states that MP3 mode should be used for swimming.

This is a purpose-led option for active listeners rather than a general replacement for noise-isolating earbuds. Check file-loading requirements, return conditions and how the open-ear fit works with your usual sports gear.
