Teenage Engineering OB-4 Portable Speaker (White)

The Teenage Engineering OB-4 is a portable speaker that turns everyday listening into something you can interact with. Alongside Bluetooth, FM radio and a line input, it continuously keeps a rolling audio buffer, allowing you to return to a moment, repeat it or change the way it plays. That makes it useful as a high-quality listening companion, a speaker for a compact music setup and a source of unexpected ideas during a writing session.

Listen, then explore what you heard

The motorised tape dial is central to the OB-4 experience. When a phrase catches your attention, move back through the buffer and hear it again. Loop a section, alter playback speed and explore the musical possibilities of material that would normally pass by once. A radio fragment can become a rhythmic motif, while a familiar song can reveal a detail you had not previously noticed.

These controls are designed for immediate listening and manipulation. OB-4 is not a replacement for a conventional sample editor or a recorder with exportable files; its creative value lies in interacting with the sound in the moment. For a musician, that can be a refreshing way to discover a new rhythm or atmosphere before returning to a dedicated production instrument.

Choose the source for the session

Bluetooth provides a convenient connection for everyday music playback from compatible devices. FM radio offers a different kind of discovery, and the analogue line input brings external equipment into the system. Connect an appropriate line-level source when you want to listen to a compact synthesiser, sampler or other music device without building a larger monitoring setup.

The speaker system combines dedicated low- and high-frequency drivers in a compact cabinet. Its stereo arrangement makes it useful for personal listening and small spaces, with a sound designed to feel substantial relative to its size. A physical volume control keeps everyday operation straightforward, while the carrying handle doubles as a stand so that you can change the listening angle as well as move the unit easily.

More than the next track in a playlist

Disk mode introduces additional listening and creative functions. Ambient processing can transform captured material into a changing soundscape, while other modes provide meditative listening, noise textures and timing tools. These features give the speaker a role beyond conventional playback, whether it is providing a background atmosphere or helping you explore a small musical idea without opening a computer.

The rechargeable battery supports long sessions away from a wall socket, with running time depending on the source, volume and use. Orthoplay provides supported remote-control and update functions, while the main listening and performance controls remain on the speaker itself. The result is a product that feels complete and usable without making a phone screen the centre of every interaction.

OB-4 suits listeners who enjoy a physical connection to their music, as well as musicians looking for a portable playback system with a more playful side. Bring it to a writing session, use it around the home or connect it to a small hardware rig. It provides familiar speaker functions first, then adds a distinctive way to revisit, repeat and reshape the sound around you. This listing supplies one OB-4 speaker in the selected finish.
