Nank Runner Diver2 Pro

4.1

$122.99as of Jun 7

— 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

— Bulkier and thicker than Shokz's slimmer frames to fit the MP3 module
— Instrument separation suffers due to the bone-conduction approach

Higher ratedRanked #2 in Best Bone Conduction Headphones

Shokz OpenRun

4.4

$129.95as of Jun 7

The standard OpenRun is the budget-friendly Shokz pick and the model Tom's Guide gave its Editor's Choice award. SoundGuys rates it a solid mid-pack 7/10, calling it one of the best options in a niche market. You trade the Pro 2's richer sound and USB-C charging for a lower price and a tougher IP67 rating.

Strengths

— IP67 rating means full sweat and dust resistance, more robust than the pricier OpenRun Pro 2's IP55
— Light 26g titanium frame that reviewers say disappears during long runs
— 8-hour battery with a 10-minute quick charge giving 1.5 hours of playback

Watch-outs

— Single bone-conduction driver with no air-conduction speaker, so bass is thin
— Proprietary magnetic charging connector instead of USB-C
— No companion app or custom EQ

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

The value pick of the lineup: tougher IP67 sealing than the OpenRun Pro 2 but a single driver with weaker bass, and no onboard storage like the Shokz OpenSwim Pro, Mojawa Run Plus or Nank Runner Diver2 Pro carry for swimming.
