The OB-4 continuously records everything you listen to on a two-hour looping tape. With a simple flick of your fingers, you can rewind, manipulate time, and create loops, whether intentionally or inadvertently. The instant rewind feature on the radio is merely one of the many remarkable capabilities of the OB-4.

Natural Sound

Four meticulously designed speaker components provide exceptional sound quality and a stereo experience that envelops the entire space. An aerodynamically optimized bass reflex duct ensures rich, authentic bass.

Up to 72-Hour Battery Life

Consider the experience of conventional radio listening for an entire week without the need for recharging. The high-capacity lithium polymer battery provides approximately eight hours of continuous sound at maximum volume, or an impressive average of 40 hours on a single charge.

The Wireless Part

The OB-4 hardware platform is compatible with both high-definition Bluetooth classic and Bluetooth Low Energy standards. It operates seamlessly with the ortho remote, allowing for wireless volume adjustment.

Smart Antenna

Teenage Engineering has dedicated years to refining the antenna, ensuring that you do not need to worry about it. Additionally, for challenging listening environments, they have incorporated a precisely calibrated smart spiral antenna that seamlessly fits into the handle.

Motorized User Interface

Utilize your fingers to grasp, rotate, and engage with the audio through the digitally controlled volume knob and tape reel. Teenage Engineering refers to this as an advanced user experience. It is equipped with a brushless motor, a hall-effect sensor, and an intelligent motor control algorithm.

Turn Your Mind On with Disk Mode

By bypassing conventional inputs such as line in, Bluetooth, and FM radio, one enters disk mode. In this mode, Teenage Engineering will persistently innovate and introduce new experimental features for the OB-4. This serves as their public research environment, enabling them to investigate and prototype the full potential of this media instrument, as they refer to it.

For now, there are three functions on the disk: ambient, karma, and metronome:

• Ambient lets you zone out to a drone generated by snippets of a radio broadcast.
• Metronome provides high-def stereo recording at one beat per minute,up to 800 BPM.
• Karma is a 30-in-1 musical mantra boxyour spiritual companion.
