Shokz OpenMove vs Nank Runner Diver2 Pro

Buy the Shokz OpenMove for everyday running, cycling and calls where you want a light, proven open-ear set with strong voice quality. Buy the Nank Runner Diver2 Pro if you swim, need far longer battery life, or want built-in MP3 playback without a phone. The OpenMove is lighter and has the more established bone-conduction tuning; the Nank wins on water protection, battery and offline storage.

• Choose the Shokz OpenMove if you want a light, simple open-ear headset for running, riding and phone calls and don't need to swim with it.
• Choose the Nank Runner Diver2 Pro if you swim, train for hours, or want 32GB of onboard music so you can leave your phone behind.
