beer sound clarity and richer sound quality.
NOTE: When you make or receive a phone call, immersive audio is temporarily set to
O (see page 32).

Charging case Up to 3 hours
NOTES:
• When the earbud baery level is low, a 20-minute charge with the case closed
powers the earbuds for up to 2 hours.
2
• A full charge powers the earbuds for up to 6 hours with immersive audio set to O
(up to 4 hours with immersive audio set to On).
3
• When the case is fully charged, you can fully charge the earbuds up to 3 times.
4
• When the earbuds are inside of the case, the case charging time varies.
1 Testing conducted by Bose in July 2023 using production-representative Bose QuietComfort Ultra Earbuds and Bose
QuietComfort Ultra Earbuds charging case. Quick charge testing consisted of inserting earbuds with baery depleted (to the
point of no audio playback) into a fully charged case and charging earbuds for 20 minutes, then resuming Bluetooth A2DP
audio playback with volume set to loudness of 75dBSPL, 3-band EQ set to zero, in Quiet Mode (full noise cancellation) with
Immersive Audio switched o, resulting in up to 2 hours playback time before baery depletion. Time to achieve fully charged
earbuds was determined by inserting earbuds with baery depleted (to the point of no audio playback) into a fully charged
case and charging earbuds to 100% baery charge. Baery life varies based on seings and usage.

3 Testing conducted by Bose in June 2023 using production-representative Bose QuietComfort Ultra Earbuds and a variety of
music tracks using A2DP Bluetooth audio. Volume set to playback loudness of 75dBSPL, 3-band EQ set to zero, in Quiet Mode
(full noise cancellation). With Immersive Audio o, playback time was up to 6 hours before baery depletion. With Immersive
Audio on, playback time was up to 4 hours before baery depletion. Baery life varies based on seings and usage.
4 Testing conducted by Bose in July 2023 by inserting production-representative Bose QuietComfort Ultra Earbuds with baery
depleted (to the point of no audio playback) into a fully charged Bose QuietComfort Ultra Earbuds charging case and charging
earbuds to 100%, then resuming audio playback until baery depletion. Testing resulted in three complete charging cycles by
