Yes. Your WONDERBOOM 2 is IP67 rated and has been tested to withstand up to 1 meter of submersion for up to 30 minutes. Make sure the weather door for the 3.5mm auxiliary port and micro-USB port is on securely before bringing your Ultimate Ears Speaker near water. However, the micro-USB charging cable included with your WONDERBOOM is not waterproof. Never charge your Ultimate Ears Speaker if the micro-USB port, charging cable or connectors are wet, dirty or damaged. Always charge your speaker with a clean, dry micro-USB connector. If you think your cable or connector has been compromised in any way by water or other contaminants, do not use it to charge your speaker. Contact us for a replacement cable.
