Bose Immersive Audio creates a speaker-like listening experience through earbuds, making sound feel like it's coming from in front of you rather than inside your head.

How It Works

Uses onboard sensors and Bose processing to create spatial audio. Unlike competitors, it works with any stereo source—no special content required.

Two Modes

• Still: Audio stays fixed in front (for seated listening)
• Motion: Audio tracks your movement (for walking/exercise)

What It's Best For

• Orchestral and classical music
• Live recordings
• Acoustic performances

Less Impactful For

• Electronic music
• Podcasts
• Heavily processed audio

Battery Impact

Reduces battery life from 6 hours to approximately 4 hours.

The Verdict

Worth trying. Easy to toggle on/off via earbuds or Bose app. Many users love it; others use it selectively. It's a key differentiator of the QuietComfort Ultra lineup.
