The super-portable WONDERBOOM delivers uncompromising sound quality with crisp and clear 360-degree sound, immersive, balanced bass and drop-proof from up to five feet. 10-hour battery life and 100-foot wireless Bluetooth range. Both waterproof and worry-proof, WONDERBOOM is IPX7 rated (so it can be immersed in water up to one meter for up to 30 minutes) and floats on its own. All functionality is built in, no app required. Power on, pair, press play, pause or skip a song directly from the speaker. Connect two WONDERBOOM speakers for more sound.
