The OB–4 is not just a portable speaker; it is a "media instrument" designed to revolutionize how you interact with sound. Combining high-fidelity audio with a world-first "magic" looping tape feature, it allows you to rewind live radio, remix on the fly, and experience music with tactile, motorized precision. Whether you are at home or on a holiday, the OB–4 delivers a room-filling, natural stereo field that sounds significantly larger than its ultra-slim profile suggests.

The Magic Tape: Never Miss a Beat

Have you ever wished you could instantly rewind the radio to hear the title of a song? The OB–4 memorizes everything you listen to on an endless looping tape with a rolling 2-hour recording window. Rewind, time-bend, and loop any audio source—whether it's FM radio or Bluetooth—at the flick of your fingertips.

Natural, Room-Filling Sound

Four tailor-engineered speaker elements—two 4-inch bass drivers and a pair of neodymium tweeters—deliver a crystal-clear, open stereo field. Powered by 38 watts per channel, it produces around 100 decibels of incredible sound. The flow-optimized bass reflex duct ensures deep, natural bass that fills the entire room despite its slim profile.

Motorized Interactive Interface

Experience the next level of user interaction. The OB–4 features a motorized user interface with digital-motion controlled volume knobs and a physical tape reel. Grab, spin, and interact with the sound physically; it’s a tactile experience that makes every adjustment feel like part of a performance.

Disk Mode: The Experimental Playground

Beyond traditional Bluetooth and radio functionality, OB–4 includes an experimental Disk Mode filled with creative audio tools and evolving software features. Currently, you can explore:

Ambient: Zone out to drones generated from any audio source.
Karma: A 30-in-1 musical mantra box and spiritual companion.
Metronome: Sync with a high-definition metronome, including 808 pitch adjustment.
Noise: Induce focus with white, brown, and pink noise frequencies.

Extraordinary Battery Life

Listen for three sleepless days on a single charge. The high-capacity Li-Po battery provides 72 hours of FM radio listening or an average of 40 hours via Bluetooth. It is built for long hauls, from your living room to your holiday destination.

Ultimate Portability & Design

OB–4 is designed for true portability. Its slim body, lightweight construction, and integrated folding handle make it easy to carry between rooms, outdoor gatherings, studios, vacations, or creative workspaces.

The handle also doubles as a stand for angled listening and houses the extended FM antenna for stronger radio reception.
