Big, detailed sound with deeper bass – Larger custom neodymium drivers deliver clear mids and highs, while the expanded stereo enclosure and larger passive bass radiator produce fuller, deeper bass. Designed and engineered by Cambridge SoundWorks in the USA.

Powerful 21W output – A high-performance 21W digital amplifier delivers strong volume for larger rooms, patios, outdoor spaces, and gatherings. Advanced digital signal processing provides balanced sound across volume levels.

IPX7 waterproof with 100-foot range – Built to withstand rain, splashes, and temporary immersion in up to 1 meter of water for up to 30 minutes. Advanced antenna technology provides a fast, reliable wireless connection from up to 100 unobstructed feet away. Connects with smartphones, tablets, computers, and compatible Echo devices.

Two-speaker wireless pairing – Connect two OontZ Angle 3 Pro speakers for left- and right-channel stereo separation, or set both speakers to play full stereo in different areas. Second speaker sold separately.

Up to 15 hours of playtime – Listen for up to 15 hours at 2/3 volume level. The USB power port can charge a compatible phone while playing, and the built-in microphone supports hands-free calls. Includes a USB-C charging cable and 3.5 mm audio cable.
