Ranked #5 in Best Bone Conduction Headphones

Nank Runner Diver2 Pro

4.1

$122.99as of Jun 7

The Nank Runner Diver2 Pro (from Naenka) is the most aggressively waterproofed pick here, with an IP69 rating that beats the IP68 of its rivals, plus 32GB storage and Bluetooth 5.4. Soundphile Review scored it 7/10 and TechRadar called it one of the best waterproof headphones available. Sound is the weak spot: very midrange-forward with little bass.

Strengths

— Class-leading IP69 waterproofing using nano coating and ultrasonic welding, the highest rating in this group
— 32GB onboard MP3 storage plus Bluetooth 5.4 for above-water streaming
— 35-degree adjustable ear hook switches between open-ear and a noise-canceling mode

Watch-outs

— Sound is heavily midrange-focused with rolled-off bass and treble; reviewers note minimal physicality
— Bulkier and thicker than Shokz's slimmer frames to fit the MP3 module
— Instrument separation suffers due to the bone-conduction approach

Higher ratedRanked #1 in Best Bone Conduction Headphones

Shokz OpenRun Pro 2

4.6

$179.95as of Jun 7

The OpenRun Pro 2 is the consensus pick for the best-sounding bone conduction headphones, pairing a bone-conduction driver with a small air-conduction speaker to push bass that the form factor usually can't manage. SoundGuys calls them the cream of the crop and TechGearLab ranked them #1 of 10 running headphones tested. The IP55 rating and high price are the main caveats.

Strengths

— DualPitch dual-driver design adds a dedicated air-conduction speaker for noticeably deeper bass than bone-conduction rivals
— 12-hour battery life, up from 10 hours on the original OpenRun Pro
— Switched to a universal USB-C charging port, ending the proprietary magnetic dock

Watch-outs

— IP55 rating is a step down from the IP67 of the standard OpenRun, so they cannot be submerged
— Volume buttons are hard to distinguish by touch, especially with gloves
— Microphone struggles in windy conditions

How they stack up

Nank Runner Diver2 Pro

The most waterproof option here, with an IP69 rating that exceeds the IP68 Shokz OpenSwim Pro and Mojawa Run Plus, but its midrange-only sound is weaker than all of them, including the air-conduction Shokz OpenRun Pro 2.

Shokz OpenRun Pro 2

The best sound in this group thanks to its air-conduction driver, but unlike the Shokz OpenSwim Pro, Mojawa Run Plus and Nank Runner Diver2 Pro it has no onboard storage and its IP55 rating means it can't be submerged like the IP67 Shokz OpenRun.
