Teenage Engineering OB-4 + Case + Ortho Remote

The Magic Radio: Teenage Engineering OB–4

Meet the OB–4, the portable, high-fidelity loudspeaker that memorizes everything you play. This isn't just a speaker; it's an interactive listening instrument. The OB–4 continuously records a two-hour loop of any audio played through it, whether from line-in, Bluetooth, or FM radio. This "magic rewind" feature allows you to instantly rewind, time-bend, and loop any moment, opening up a new world of sonic interaction.

Engineered with two 4'' bass drivers and a pair of neodymium tweeters, the OB–4 delivers a crystal clear, open, and natural sound with a deep bass. Its high-capacity li-ion battery provides up to 72 hours of radio listening or 40 hours of Bluetooth playback on a single charge. The motorized user interface, featuring a digital-motion controlled volume knob and tape reel, offers a uniquely tactile and engaging way to interact with your sound.

Beyond its core functions, the OB–4 features an experimental "disk mode" with creative tools like an ambient drone generator, a precision metronome, and a mantra box. With its versatile handle that doubles as a stand and an antenna, and its sleek, ultra-thin design, the OB–4 is built to be your companion for listening, creating, and experimenting anywhere.
