Teenage Engineering OB-4 Magic Radio Portable Bluetooth Speaker in Black

The Teenage Engineering OB-4 Magic Radio in Black is a slim, ultra-portable bluetooth loudspeaker with a sound far bigger than its footprint. Combining deep, natural bass, crystal-clear stereo imaging and a unique motorised interface, it is as inspiring to use as it is to listen to. With FM radio, bluetooth, line-in and the experimental disk mode on tap, OB-4 is a powerful media instrument for everyday listening, creative practice and live performance.

Designed to go wherever you do, OB-4 offers up to 72 hours of FM listening or 40 hours over bluetooth from a single charge, with an integrated handle that doubles as a stand for relaxed listening angles. Under the minimalist surface you will find clever tricks like an endless looping tape that lets you rewind live radio, plus a growing suite of experimental tools in disk mode. Whether you are soundtracking your kitchen, rehearsing in the studio or remixing on the move, OB-4 is built to keep you listening, creating and exploring.

Ultra Portable Magic Radio

OB-4 is an ultra thin, book-like bluetooth loudspeaker that is easy to grab, carry and place anywhere. The compact footprint and integrated handle let you move seamlessly from living room to garden, rehearsal room to holiday apartment, without sacrificing sound quality. It is a true everyday companion that fits into your life rather than demanding its own space.

Natural, Room-Filling Sound

Inside the sleek chassis are four tailor-engineered speaker elements and a flow-optimised bass reflex duct, delivering deep, natural bass and a wide stereo field that fills the room. The result is open, detailed audio that flatters everything from radio shows and podcasts to synth jams and DJ mixes, helping you hear more of the music and make better decisions when you are creating.

Motorised Interface And Endless Tape

The motorised user interface invites you to physically interact with sound. A digital motion-controlled volume knob and tape reel respond to your touch, letting you grab, spin and scrub audio in real time. OB-4 continuously records what you hear onto an endless looping tape, so you can instantly rewind live radio to catch a song title, loop a groove, time-bend a moment or experiment with happy accidents.

Disk Mode And Creative Tools

Beyond standard line-in, bluetooth and FM, disk mode unlocks a playground of evolving features. Current functions include ambient, karma, metronome, noise and loop, turning OB-4 into a creative instrument as well as a speaker. Paired with the orthoplay app and ortho remote, you can access updates, control volume wirelessly and stay on top of the latest experiments Teenage Engineering add to this constantly developing platform.

Studio Friendly Performance

A low-latency line input makes OB-4 a capable portable studio monitor. Plug in instruments, a record player or any audio device and monitor with confidence, or use the FM signal to connect to compatible Teenage Engineering gear. With looping, metronome and ambient tools on hand, OB-4 can sit at the heart of your practice setup, letting you live remix, layer ideas and explore new textures in the moment.
