No. Bluetooth does not work under water. The Endurance DIVE however has a built-in MP3 player for music, and is IPX7 waterproof. This means you can use the headphones submerged to 1 meter depth, up to 30 minutes at a time. Also note that for normal swimming, you won't be submerged all the time, so the headphones should be waterproof for the duration of your swim.
