Product Features:
Feel your music more
Breakthrough spatial audio for more immersive listening that makes your music feel more real than ever before — no matter the content or source. World-class noise cancellation and sound tailored to you. And a design that feels so good to wear. Say less. (Listen more.)

Listen longer with up to 24 hours total play time
QC Ultra Earbuds give you up to 6 hours of listening time (up to 4 with Immersive Audio) while the included case holds up to 3 additional full charges . Pop the buds in the case for up to 2 hours of music from a 20-minute charge.

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 cancelling earbuds and sound that's tailored to you.

High-quality earbuds for comfort and stability
Swap between nine potential combinations of eartips and stability bands. 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.

Crystal-clear, natural-sounding phone calls
Enjoy clear, natural-sounding phone conversations. Noise-rejecting mics and 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.

A powerful wireless connection with advanced Bluetooth 5.3
Bose Bluetooth earbuds offer a strong, continuous connection within 30 feet of your device. Choose single- or multi-point to keep your phone, tablet, and work or school computer paired or just focus on one.

Different listening modes for different environments
When it’s time to tune in and jam out, use Quiet Mode. 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.

Simple touch-free device controls
Wireless earbuds that give you full control. Play or pause music, change the volume, and switch tracks. You can even answer calls and change the noise cancellation level, all without ever touching your phone.

Customize your experience with the Bose Music app
Take personalization even further with Adjustable EQ settings in the Bose Music app. Control bass, mid-range, and treble levels as you go. Or use the app to check battery life, customize a shortcut, and manage connected devices.
