Description
- The Teenage Engineering OB-4 Magic Radio Hi-Fi Portable Speaker is a portable high-fidelity Bluetooth speaker, recorder, and experimental “Magic Radio” system that lets you stream audio via Bluetooth, FM radio, line-in, or disk mode while continuously recording everything you hear onto a rolling two-hour loop tape so you can rewind, time-bend, and remix audio in real time; built around a stereo hi-fi system with dual Class-D amplifiers and precision-tuned woofers and tweeters, it delivers wide, dynamic, room-filling sound with deep natural bass, while its smart antenna ensures strong FM reception and its folding handle doubles as both a stand and extended antenna, and with up to 40 hours of Bluetooth playback or up to 72 hours of FM listening on a single charge plus UV-resistant construction, motorized tactile controls, and support for Ortho Remote and the Orthoplay app, it functions as both a premium portable speaker and an evolving experimental audio instrument.
