QuietComfort Ultra Earbuds offer Bose’s most advanced technologies, including CustomTune, enhanced noise cancellation, audio quality, voice pickup, and features like Spotify Tap, SimpleSync, and Snapdragon Sound / Google Fast Pair for compatible devices. QuietComfort Earbuds offer strong everyday performance with customizable shortcuts and voice command via the Bose QCE app.

The Bose QCE app is specifically designed to work with QuietComfort Earbuds, providing EQ adjustment, adjustable ANC, voice assistant, tap control customization, update notifications, plus features like battery prediction, remote selfie, and voice command.

Active EQ is an internal equalization that tunes the frequency response to a target Bose audio curve. It adjusts the sound to maintain clarity and balance across different volume levels.

They use a patented acoustic port design, efficient drivers, and volume-optimized Active EQ to maintain clarity and deep lows even at lower volumes. A low noise floor helps reduce hiss.

They are designed for extended wear. The eartips have an extended flexible wing that spreads pressure and provides stability without compromising comfort.

Yes — they have an IPX4 rating for protection against sweat and splashing water from any angle. The interior of the charging case is also resistant to moisture retained on the earbuds, but the case’s exterior should not be exposed to water.

No — they are not designed for submersion.

Yes. The Bose Music app allows control of the earbuds, switching between Bluetooth devices, adjusting noise cancelling levels, monitoring battery, accessing updates, and setting preferences. Note: they do not support other Bose apps like Bose Connect, Hear, or SoundTouch.

Yes, but only the right earbud. When paired, the right earbud maintains the Bluetooth connection and relays audio to the left bud. If the right is removed or placed in the case, the left earbud will lose connection. Calls use the microphone system in the right earbud, so for calls you must use that one. Also, using only the right bud disables touch controls on the left; adjustments must be made via the Bose Music app or source device.

On first use, opening the charging case puts the earbuds in discoverable mode (status lights pulse blue). Then pair via Bluetooth, or preferably via the Bose Music app for guided setup. To connect to a new device later, press and hold the Bluetooth button on the case until the status light pulses slowly, or use the app. Only one device’s audio can be played at a time.

Place the earbuds into the charging case; if the case has power, it will charge the buds. The earbuds’ status lights pulse white while charging. The charging case itself can be charged either via USB-C or by placing it on a Qi-certified wireless charging pad (not included).

Yes — a quick 15-minute charge gives up to 2 hours of playback time.

They use touch controls (swipe, tap, press/hold) instead of physical buttons. Controls vary by bud (right/left) and can be customized via the app.

The Shortcut is a customizable command (e.g. skip track, check battery) that you assign via the Bose Music app, then access by pressing and holding the left earbud.

The StayHear® Max tips wrap around the earbud acoustic body (vs being mounted), allowing the buds to sit closer to the head. They create a more airtight seal, improving bass and overall audio.

To help ensure comfort, proper fit, and optimal performance. Bose recommends using the app’s eartip sizing tutorial to find the right size, and it’s common to need different sizes in each ear.

After use, gently wipe the earbuds dry and avoid letting moisture enter ports. Remove eartips and rinse with water + mild detergent, then let them fully dry before reattaching. Don’t blow air into ports or force debris.
