Listen, loop, and rewind audio on-the-go with the matte black Teenage Engineering OB-4 Magic Radio, Recorder, and Speaker with Bluetooth. Source your audio by streaming via Bluetooth from a mobile device, use the smart antenna to dial in FM radio, plug in an audio device via the 3.5mm line in jack, or access the experimental disk mode. Whatever you play is continuously recorded on a rolling 2-hour loop tape, so you can rewind and listen again. Whey playing audio, clear and dynamic sound emit from the OB-4's two built-in woofers and tweeters powered by two 38W Class-D amplifiers.

Have you ever wished you could instantly rewind when listening to the radio to hear the title of the song just played? The OB-4 continuously memorizes everything you listen to on two-hour 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-optimized bass reflex duct delivers deep, natural bass.

How about normal radio listening for a week without charging? The high-capacity LiPo battery delivers about eight hours of noise at max volume, or an average of 40 hours on a single charge.

The OB-4 hardware platform supports both high-definition Bluetooth classic and Bluetooth Low Energy standards. Works with the ortho remote for wireless volume control.

Teenage Engineering has spent years fiddling with the antenna, so you won't have to. And for those tricky listening places, they've included a fine-tuned smart spiral antenna that neatly integrates into the handle.

Use your fingers to grab, spin, and interact with the sound with the digital motion-controlled volume knob and tape reel. Teenage Engineering calls it the next level of user experience. It features a brushless motor, hall-effect sensor, and intelligent motor control algorithm.

If you skip the traditional inputs like line in, Bluetooth, and FM radio, you end up in disk mode. This is where Teenage Engineering will continuously develop new experimental features for the OB-4. It's their public research space, where they allow themselves to explore and prototype everything that this media-instrument, as they like to call it, can become.

For now, there are three functions on the disk: ambient, karma, and metronome:

• Ambient lets you zone out to a drone generated by snippets of a radio broadcast.
• Metronome provides high-def stereo recording at one beat per minute,up to 800 BPM.
• Karma is a 30-in-1 musical mantra box—your spiritual companion.

Designed to be played outdoors in public spaces and at high volume or carried on one shoulder with the speaker elements facing the head. 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.
