Teenage Engineering OB-4 Ochre

The Teenage Engineering OB-4 Ochre is a portable Bluetooth loudspeaker that treats sound like a musical instrument. With its unique endless looping tape, motorised interface and powerful stereo system, it lets you rewind, sculpt and interact with whatever you are listening to, from FM radio to Bluetooth streams. Add in a huge battery life and a slim, rugged design and you have a high-fidelity speaker that is just as at home in the studio as it is on the beach, in the park or on stage.

At the heart of OB-4 is a four-speaker array with twin 4-inch bass drivers and neodymium tweeters, driven by ultra-efficient Class D amplification. The result is deep, natural low end and crystal-clear highs, with enough volume to comfortably fill a room. A flow optimised bass reflex duct and semi unified chamber design help the speaker sound bigger than it looks, delivering a wide stereo image and detailed, hi-fi sound wherever you set it down.

What sets OB-4 apart is its endless looping tape. Everything that passes through the speaker is constantly recorded, so you can wind back live radio, Bluetooth audio or line-in sources and rework them on the fly. Instead of just pressing play, you can capture moments, repeat them, and explore new ideas in real time. It turns everyday listening into a creative process, ideal for producers, DJs and anyone who likes to experiment with sound.

OB-4 is also built for life on the move. The high-capacity LiPo battery delivers up to 72 hours of listening at normal FM volume, or around 40 hours via Bluetooth on a single charge, so you can go for days without reaching for a charger. The integrated handle makes it easy to carry and can be used as a stand for flexible listening positions, while the UV-resistant finish helps the Ochre colour stay looking sharp outdoors.

Endless Looping Tape

The endless looping tape constantly records whatever you are playing through OB-4, whether it is FM radio, Bluetooth or line input. You can instantly rewind, scrub and replay audio, turning fleeting moments into material you can explore again and again. It is perfect for grabbing a riff off the radio, looping a groove from a playlist or capturing inspiration in the moment.

Motorised Interface

OB-4 features a motorised, digitally controlled volume knob and tape reel that move in response to your actions. This motion-controlled interface makes every adjustment feel tactile and expressive, so you are not just changing settings, you are performing them. It brings a physical, instrument-like feel to the way you interact with your music.

Disk Mode

Disk mode is OB-4s experimental playground, packed with evolving tools such as ambient soundscapes, karma and a metronome. It acts as a public research space where Teenage Engineering can prototype new ideas and push the speaker beyond traditional playback. As disk mode grows, OB-4 becomes an ever-expanding platform for sonic exploration.

Portable High-Fidelity Design

With its slim form factor, integrated handle and robust construction, OB-4 is designed to travel. The four-driver stereo configuration, fine-tuned spiral antenna in the handle and support for high-definition Bluetooth ensure that, wherever you go, you get reliable reception and immersive, high-quality sound in a compact, stylish package.

• Endless Looping Tape Engine - Constantly records everything you play through the speaker so you can rewind, scrub and loop live radio, Bluetooth or line-in audio. This opens up creative possibilities for sampling, practising and sound design that go far beyond standard portable speakers.
• Powerful Four-Driver Stereo System - Two 4-inch bass drivers and a pair of high-efficiency neodymium tweeters deliver up to approximately 100 dB of room-filling stereo sound. The flow optimised bass reflex duct and semi unified chamber design provide deep, natural bass and a wide, detailed soundstage.
• Exceptional Battery Life - A high-capacity LiPo battery offers up to 72 hours of listening at normal FM volume, around 40 hours on Bluetooth, or 8 hours at maximum volume. This long-lasting performance makes OB-4 a reliable companion for extended sessions, trips and outdoor use.
• Motorised Interface and Disk Mode - The digital-motion controlled volume knob and tape reel create a uniquely tactile way to control your sound, while disk mode adds evolving experimental functions such as ambient and metronome. Together they transform OB-4 from a simple speaker into an interactive media instrument.
