Connecting headphones to your system

You can connect headphones to your system for situations when low volume listening is needed. This can be useful, for example, to listen to audio at night without disturbing others in your home with the sound from your speakers.

Connecting headphones to a 3·2·1 or 3·2·1GS system

  • These systems do not have a dedicated headphone jack, and Bose is unable to supply or recommend a particular headphone booster/amplifier.
  • A headphone amplifier can be connected to the Audio OUT jacks on the back of the media center provided it has an RCA input, power (to amplify the signal), a headphone output, and volume control.
  • Connecting to the Audio OUT jacks does not turn off the speakers. The adjustment of the system's volume level does not affect the signal level of the Audio OUT jacks.
