How is the 2nd Gen different from the original QuietComfort Ultra Earbuds?

The second generation keeps the same CustomTune and Immersive Audio approach but refines the fit and adds Snapdragon Sound support for higher-resolution audio on compatible Android phones. Noise cancellation remains the headline feature.

Do these work with iPhone and Android?

Yes. They pair over standard Bluetooth with both, and multipoint lets you stay connected to two devices at once. Snapdragon Sound codecs only apply to supported Android phones.

How long does the battery last?

Bose rates them for roughly six hours per charge with cancellation on, less with Immersive Audio active, and the case adds several more charges. Expect to charge the case every few days with heavy use.

Can I use one earbud at a time?

Yes, either earbud can be used alone for calls or listening, which is useful for staying aware of your surroundings.

Are they good for running and workouts?

They have no official water-resistance rating for heavy sweat, so they suit commuting and light exercise better than serious training. The secure fit holds during walking and moderate activity.

What comes in the box?

You get the earbuds, the charging case, a USB-C cable and multiple ear tip sizes to tune the fit. The case supports wireless charging.

About the Bose QuietComfort Ultra Earbuds 2nd Gen Wireless ANC + Extended Warranty

The Bose QuietComfort Ultra Earbuds (2nd Gen) are true wireless noise-cancelling earbuds. This version is White Smoke, a warm off-white finish with subtle metallic accents.

CustomTune technology analyzes the acoustic characteristics of the listener's ears each time the earbuds are inserted. It then adjusts both the sound and the active noise cancellation to the ear shape and acoustic seal. Quiet Mode provides strong noise cancellation. Aware Mode lets surrounding sound through, and ActiveSense processing reduces sudden spikes in environmental noise. Immersion Mode combines noise cancellation with Bose Immersive Audio.

Bose TrueSpatial Immersive Audio places the perceived soundstage outside the listener's head, with Still and Motion modes for when the listener is stationary or moving. The earbuds support Snapdragon Sound, including aptX Adaptive and aptX Lossless, with compatible source devices. SBC and AAC codecs cover other Bluetooth devices. Bluetooth multipoint keeps the earbuds connected to two compatible devices at once.
