Product details

Room-filling sound with real presence

The OB-4 pairs two 4 inch bass drivers with a pair of neodymium tweeters to create a wide stereo image. A flow-optimised bass reflex duct is designed to deliver deep, natural bass that remains clear as you raise the volume.

  • 38 watts per channel for a bold, immersive impression
  • Ventilated bass system that balances bass with mids and highs

Connectivity and smart control

Beyond the radio, OB-4 supports line-in and high-definition wireless Bluetooth plus Bluetooth Low Energy. The ortho remote provides wireless volume control, and the orthoplay app on iOS and Android enables easy setup and streaming from popular services.

  • FM radio and line-in for flexible listening
  • Spotify, Apple Music and most major services supported

Long-lasting power for everyday listening

The built-in LiPo battery is rated for up to 72 hours of normal radio listening. At higher volume you can expect about 8 hours, and a typical charge might sustain around 40 hours of listening.

  • 72 hours for radio listening
  • 8 hours at max volume; ~40 hours per charge

Interactive, tactile features

OB-4 memorizes playback and invites manipulation with a digital-motion volume knob and a tape reel. Rewind, remix, and explore three disk-mode functions — ambient, karma and metronome.

  • Endless looping tape memory for remixing
  • Disk mode stores experimental features

Designed for life on the move

The sturdy handle doubles as a stand, and a smart spiral antenna in the handle provides an extra FM boost when needed. Optional OB-4 carry bags and straps come in several colors for easy transport.

  • Carry handle for portability and stand function
  • Spiral antenna in handle for better FM reception
  • Colorful carry accessories available
