Portable Speaker Teenage Engineering OB-4 (White)

Teenage Engineering OB–4 is more than just a Bluetooth speaker. It is a new generation portable audio system that combines rich stereo sound, FM radio, real-time recording functionality, and an innovative approach to interacting with sound. Thanks to its built-in “endless loop tape,” the OB–4 can store the last two hours of listening and allows you to rewind, loop, and reinterpret music in the moment — just like a DJ or sound experimenter would.

The speaker system is equipped with two powerful 38W Class D amplifiers and four speakers (two high-frequency and two low-frequency), creating a rich, full sound with deep bass and clear details in the mid and high frequency ranges. The frequency range from 52 to 25,000 Hz ensures natural reproduction of both voice and music.

The OB–4 supports Bluetooth Classic (AAC), Bluetooth 5.0 LE, 3.5 mm AUX input, and has a built-in FM radio. Additionally, there is a unique Disk mode available, in which the user can activate experimental features such as Karma, Metronome, or Ambient, creating their own sound space. The built-in battery provides up to 72 hours of radio listening or up to 40 hours of Bluetooth operation at medium volume, making the device ideal for travel, performances, or working outside the studio.
