Runner Diver2 is Nank's answer to the Shokz OpenSwim Pro at roughly half the price. Nank, which used to sell as Naenka, lists an IP68 rating and 32 GB of built-in storage, enough for thousands of songs, and notes that only the MP3 mode works underwater, because Bluetooth does not. On land it pairs over Bluetooth 5.3 for runs and rides, and a triple-click switches modes. The battery is rated at 10 hours at 60% volume, with a 1.5 hour magnetic charge. Nank says its leakage reduction cuts sound leakage by 90% and that it uses a 16 mm speaker. The newer version adds an integrated silicone case and accessories. At 32 g it is heavier than the Shokz running models. The current sale price is $111.99 against a regular $139.99, and the store lists a 1-year warranty, shorter than the 2 years from Shokz and Mojawa.
Who it is for
Runners and cyclists who also swim and want offline music for less than Shokz charges.
