Shokz OpenSwim Pro vs Nank Runner Diver2 Pro

Both are open-ear bone conduction headphones built for swimming, with 32GB of MP3 storage and Bluetooth 5.4. The Shokz OpenSwim Pro is the safer pick for most swimmers: it has a deeper track record, a nickel-titanium headband that holds its shape, and a 4.5 rating across thousands of owners. The Nank Runner Diver2 Pro adds an active noise-canceling mode, a higher IP69 rating and a longer 10-hour battery, which suits pool and open-water swimmers who want to block wind and crowd noise. Build quality and support favor Shokz; feature count favors Nank.

• Choose the Shokz OpenSwim Pro if you want the proven, comfortable fit and a brand with a long record in bone conduction audio.
• Choose the Nank Runner Diver2 Pro if you want noise-canceling modes, a longer battery and the highest water rating for the same kind of swimming use.
