feel realer than ever before — no matter the content or source. World-class noise
cancellation and sound tailored to you with a fresh and sophisticated design in the
limited-edition Moonstone Blue color. Say less. (Listen more.)

Immersive audio. Feels more real.
Bose Immersive Audio pushes the boundary of what it means to listen. It spatializes
what you’re hearing by taking it out of your head and placing it in front of you —
putting you in the acoustic sweet spot. Sound so real it’s almost like you can reach out
and touch it? Yes, please. Say hello to the most natural listening experience.

World-class noise cancellation and sound shaped to you.
The magic of CustomTune technology: it analyzes your ears and adapts the sound and
active noise cancelling to their unique shape. The result? World-class noise
cancellation and sound that’s tailored to you. So you can dance harder, focus better,
and hear your fav song like it’s the first time all over again.

Modes for how you want to listen.
When it’s time to tune in and jam out, use Quiet Mode to tap into world-class noise
cancellation. But sometimes you need to pay attention. That’s why Aware Mode allows
enough transparency to hear your surroundings or engage in conversation without
taking out an earbud. Immersion Mode engages full noise cancellation with
Immersive Audio turned on.

High-quality earbuds for comfort and stability.
While they’re designed for all ears, these The limited-edition Moonstone Blue earbuds
are uniquely shaped to yours. And now it’s easier to swap between nine potential
combinations of eartips and stability bands to help you find the right fit. The soft,
umbrella-shaped tips seal off the opening of your ear to reduce outside noises. And
stability bands hug the contours of your ears for a snug fit.

Go ahead, listen longer with up to 24 hours total play time.
QC Ultra Earbuds themselves give you up to 6 hours of listening time (up to 4 with

music from just a 20-minute charge.***

Crystal-clear, natural-sounding phone calls.
No more “huh?” when you’re trying to just say “hello.” Noise-rejecting mics focus on
your voice and filter out background noise for the clearest calls. They’ll play through
both or a single earbud, whatever works for you.

Swipe, tap, touch to get into the music.

right on the earbuds themselves. You can even answer calls and cycle through modes,
all without ever taking out your phone.

* Testing conducted by Bose in June 2023 using production-representative Bose QuietComfort Ultra
Earbuds and a variety of music tracks using A2DP Bluetooth audio streaming at RSSI signal strength of
75dBm. Volume set to playback loudness of 75dB, 3-band EQ set to zero in Quiet Mode (full noise cancellation). With Immersive Audio off, playback time was up to 6 hours before battery depletion.
With Immersive Audio on, playback time was up to 4 hours before battery depletion. Battery life
varies based on settings and usage.

** Testing conducted by Bose in July 2023 by inserting production-representative Bose QuietComfort
Ultra Earbuds with battery depleted (to the point of no audio playback) into a fully charged Bose
QuietComfort Ultra Earbuds charging case and charging earbuds to 100%, then resuming audio
playback until battery depletion. Testing resulted in three (3) complete charging cycles by the case
before a full charge was no longer possible.
