A:Answer They have an IP rating that makes them safe for swimming. However, it might not be a great choice for that. Bluetooth won't work well a couple inches below water. If you are paired with a waterproof smartwatch the sound cuts in and out as you swim. I've tried it, so I know. If you have a phone on the edge of the pool and you stay in range, it's better, but not great still. Also, the water gets in and out of your ear as you swim, so it sounds a bit odd. There is not waterproof seal to your ears, so water gets in between them and your ear. Lastly, the left ear has a touch sensitive button which can get triggered by water, so it may make the volume fluctuate as you swim. I'd say use these in the Jacuzzi or shower, but swimming is less ideal.
