Teenage Engineering OB–4 – Smart Portable Bluetooth Speaker with FM Radio and Looping
The Teenage Engineering OB–4 is a revolutionary portable speaker system that combines exceptional sound quality with smart looping, FM radio, and real-time audio manipulation features. Whether you’re listening, performing, or experimenting, the OB–4 is a creative audio tool like no other—crafted with precision, designed for portability, and powered by innovation.
At the heart of the OB–4 is a pair of custom 4” bass drivers and neodymium tweeters, powered by a 38-watt stereo class D amplifier for crystal-clear playback and surprisingly powerful sound. What makes OB–4 truly unique is its integrated endless looping system: it continuously records everything you play (up to 2 hours), letting you rewind, loop, and remix live radio, Bluetooth streams, or line-in audio in real time.
With FM radio reception, Bluetooth 5.0, line-in, and a smart rotary interface, the OB–4 offers a tactile, intuitive user experience. Choose from “disc modes” like Ambient, Metronome, or Karma to explore meditative and experimental audio tools. Its sleek, minimal design and optional handle (which doubles as a stand or carrying grip) make it equally at home in your living room, on the street, or in the studio.
