Bose QuietComfort Ultra Earbuds (2nd Gen)

QuietComfort Ultra Earbuds (2nd Gen) offer all the same features as their predecessor, QuietComfort Ultra Earbuds, plus:

• Improved call quality through AI-based background noise suppression
• Wireless charging
• Improved ActiveSense (adaptive noise cancellation) technology
• Case battery level reporting in the Bose app
• Option to disable touch controls via the Bose app

ActiveSense is a type of adaptive Aware Mode that listens for very loud environmental sounds and selectively applies noise cancellation appropriate for both the loudness and duration of the detected sound. This way, you can remain aware of your surroundings, without having your music drowned out by interruptions like passing vehicles and loud appliance motor noises, such as a coffee grinder or blender. With this update of ActiveSense, the experience is refined so the changes in noise cancellation levels are less noticeable, contributing to an overall smoother adaptive Aware Mode experience. ActiveSense can be enabled and disabled in the Aware Mode setting.

Immersive Audio allows you to hear audio as if it were coming from beyond your QuietComfort Ultra Earbuds (2nd Gen), thereby allowing for a more spacious, natural listening experience. Your music and other audio will have a wide sound stage in front and to the sides, just as if you were listening to a pair of stereo speakers and seated at the sweet spot between them.

Bose CustomTune audio calibration is a proprietary Bose technology that optimizes the audio playback you hear based on the unique physical properties of your ear and ear canal. It works by playing a specially designed calibration tone as the welcome chime, each time you power on the earbuds while wearing them. It then measures how the shape of your ear uniquely modifies that sound. The earbuds use that information to adjust their sound to your ears, creating a more balanced, authentic audio experience.

The left and right earbud surfaces are the same, but the controls vary depending on whether you are listening to audio or on a phone call.

When listening to audio:

• Swipe up or down for volume control
• Tap once to play or pause content
• Tap twice in quick succession to skip forward
• Tap three times in quick succession to skip back

• Press and hold the earbud surface to access a favourite listening mode, and release when the desired mode is announced. The default shortcut function on both buds is to cycle through three listening modes:
  • Quiet Mode (full noise cancelling)
  • Aware Mode (full audio transparency to hear outside sound)
  • Immersion (full noise cancellation with Immersive Audio)

• You can create additional modes or remove modes you don’t want using the Bose app.

For phone calls:

• Swipe up or down for volume control
• Tap once to accept an incoming call; if you are already on a call, and a second call is coming in, tap once to accept the second call and place the first call on hold
• Tap twice in quick succession to decline a call, to end a call already in progress, or to decline a second incoming call while you’re already on a call

Yes. You can use a compatible third-party wireless charger (not provided) to charge the case. For best results, centre the button (located on the back of the case) on the wireless charging pad. The charging case LED will glow solid amber to indicate the case is centred correctly and has begun charging.
