Sony WF-SP900

Whether you're running, in the pool, or at the sea, the waterproof sports headphones WF-SP900 take you further than ever before. With a completely wireless design and 4 GB of built-in storage, you can listen to music anywhere. The built-in storage holds up to 920 tracks. With the WF-SP900 waterproof headphones, rated IPX5/8, you can dive up to 2 meters deep in fresh and saltwater.

In Ambient Sound mode, you are not isolated from the outside world. Your favorite music blends with the sounds around you, allowing you to hear what's happening around you. Alternatively, announcements and other voices can be heard in Voice mode. When fully charged, the headphones allow for three hours of music playback via Bluetooth. The case provides additional full charges of three hours each, extending the total wireless playback time to up to 12 hours. Music stored in the built-in memory can be played for up to six hours, and with additional full charges from the case, playback can be extended to up to 21 hours.

To control the volume, tap twice on the left side of the earbud to decrease the volume, and twice on the right side to increase it. A single press of the left button toggles the Ambient Sound mode on or off, while a double press switches the sound quick settings. The right button allows you to play and pause tracks, skip to the next track, go back to the previous track, or answer calls. Press and hold to activate voice control and other functions.

The WF-SP900 comes with a lightweight neckband that allows you to swim without worries.
