Personalized sound in three steps

Listening modes

Listening modes are preset sound and noise cancellation settings that you can switch between depending on your listening preferences and environment. Choose one of the three pre-set modes - Quiet, Aware, and Immersion - or create up to seven custom modes yourself.

Quiet Mode

In Quiet Mode, you block out background noise with the world's best noise cancellation. Full noise cancellation and Bose-optimized stereo sound.

Aware Mode

Aware Mode provides enough acoustic transparency to hear specific sounds from the surrounding environment, so you can hear ambient sounds or have a friendly conversation.

Immersion Mode

Immersion Mode. Full noise cancellation and immersive sound. Allows you to block out distractions and immerse yourself in realistic sound.

Perfect fit

For the most comfortable fit, choose from 3 sizes of silicone tips (S, M, L). The ear tips are very soft, yet they sit securely in your ears and evenly distribute contact, providing a comfortable seal and isolating external noise. Stabilizing arches encompass the contours of the outer parts of your ear, ensuring a secure fit and ensuring that the tips stay in place. Choose from 9 possible combinations of silicone tips and stabilizing arcs to choose the most suitable one for you.

Up to 24 hours of playback

Enjoy Bose QuietComfort Ultra headphones throughout the day. The battery life on a single charge reaches 6 hours, and the charging case provides three additional charges (compared to two additional charges in the previous version).

Clearest phone calls

With four external microphones, Bose QuietComfort Ultra headphones confidently capture and isolate your voice from background noise. The headphones isolate your voice and focus on it, and the noise cancellation algorithm filters out ambient noise for clearer sound during calls. All of this happens in real time, ensuring that your voice will always be clear and crisp even in noisy or windy conditions. Use one or two headphones for the clearest and most natural-sounding phone calls.

Touch controls

Play/pause music, adjust volume, switch modes, and skip tracks with a simple touch or swipe right on the headphones.

Bose Music app
