Charging case Up to 2 hours
NOTES:
• When the earbud baery level is low, a 20-minute charge powers the earbuds for
up to 3 hours.
2
• A full charge powers the earbuds for up to 8.5 hours.

1 Testing conducted by Bose in June 2024 using production-representative Bose QuietComfort Earbuds and Bose
QuietComfort 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), resulting in
up to 3 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.

4 Testing conducted by Bose in June 2024 by inserting production-representative Bose QuietComfort Earbuds with baery
depleted (to the point of no audio playback) into a fully charged Bose QuietComfort Earbuds charging case and charging
