How is the 2nd Gen different from the first QuietComfort Ultra earbuds?

The main addition is ActiveSense, which smooths sudden loud spikes in surrounding sound, including in Aware Mode. Noise cancellation, CustomTune and Immersive Audio carry over.

How long does the battery last?

About 6 hours per charge in Quiet or Aware Mode, or about 4 hours with Immersive Audio. The case holds roughly three extra charges, for about 30 or 23 hours total.

Do they work with iPhone and Android?

Yes. They use standard Bluetooth 5.4 and pair with either platform; the Bose app is available for both.

Can I use just one earbud?

Yes. Either earbud works alone for calls and listening, which helps stretch battery life.

What comes in the box?

The earbuds, charging case, USB-C cable and nine combinations of eartips and stability bands.

Are they good for running and workouts?

They have no official water-resistance rating, so sweat-heavy training is a risk. The stability bands keep them in place for light exercise.
