introducing OB–4, the portable high fidelity loudspeaker with two 4'' bass drivers and a pair of neodymium tweeters that deliver crystal clear, open natural sound with 38 watts per channel — that's around 100 decibels
of incredible sounding stereo. listen using line input, bluetooth, FM radio and disk. the interface is minimal, with only the things you really need. yet if you look below the surface, there's a lot more than meets the eye.
have you ever wished you could instantly rewind when listening to the radio, to hear the title of the song just played? OB–4 continuously memorises 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 radio is just one of the OB-4's magic tricks.
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 OB–4 hardware platform supports both high-definition bluetooth classic and bluetooth low energy standards. works with ortho remote for wireless volume control.
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 in the handle.
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 OB–4. 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.
