The OB�4 magic radio redefines portable audio with its revolutionary endless looping tape that captures and memorises everything you play. This incredible sounding hi-fi stereo features wireless audio, line-in connectivity, and represents the true evolution of radio technology. With its unique rewind and remix capabilities, you can grab, spin and interact with sound using intuitive digital-motion controls that respond to your touch.
Four precision-engineered speaker elements work in harmony to create pure quality sound with a stereo field that fills entire rooms. The flow-optimised bass reflex duct collaborates with environmental surfaces to produce deep, natural bass response. Built for outdoor use and public spaces, the OB�4 can be carried comfortably on one shoulder with speakers facing toward your head, though it’s worth noting that passers-by are assumed to share your musical taste.
The high-capacity lithium polymer battery provides exceptional endurance – up to a week of normal radio listening or approximately 40 hours average playback on a single charge. For those who prefer maximum volume, expect around 8 hours of continuous play. The iconic folding handle doubles as both a carrying solution and adjustable stand for relaxed listening positions.
Beyond traditional inputs like line-in, Bluetooth and FM radio, the OB�4 offers a special disk mode featuring three distinct functions: ambient, karma and metronome. The hardware platform supports both high-definition Bluetooth classic and the emerging BLE audio standard, ensuring compatibility with current and future devices.
