Have you ever wished you could instantly rewind when listening to the radio, to hear the title of the Song just played? OB4 continuously memorizes everything you listen
To on an endless looping tape*. Rewind, time-bend, and loop at the flick of your fingertips. On purpose or by accident. Instant rewind on the radio is just one of the OB-4s magic tricks.
Natural sound
Four tailor-engineered speaker elements deliver pure quality sound and a stereo field that fills the entire room. A flow-optimised bass reflex duct delivers deep natural bass.
72 hrs listening
How about normal radio listening for a week without charging? The high capacity lipo battery delivers about 8 hours of noise at max volume, or an average of 40 hours on a single charge.
The wireless part
The OB4 hardware platform supports both high-definition bluetooth classic and bluetooth low energy standards. Works with ortho-remote for wireless volume control.
Smart Antenna
We've spent years fiddling with the antenna so you won't have to. And for those tricky listening places, we've included a fine-tuned smart spiral antenna that neatly integrates into the handle.
Motorized user interface
Use your fingers to grab, spin and interact with the sound. Digital-motion-controlled volume knob and tape reel. We call it the next level of user experience.
Turn your mind on with disk mode
If you skip the traditional inputs like line in, bluetooth and FM radio, you end up in disk mode. this is where we will continuously develop new experimental features for the OB4. it's our public research space, where we allow ourselves to explore and prototype everything that this media-instrument, as we like to call it, can become. for now, there are three functions on the disk; ambient, karma, and metronome.
The handle-stand
Designed to be played outdoors, in public spaces, and at high volume; carried on one shoulder with speaker elements facing the head. note: it is assumed that passers-by share the same musical taste. Or why not give it a home in your kitchen? with any luck, the iconic handle makes it a breeze to carry anywhere, and can even be used as a stand for a more relaxed listening position.
