CHARGING TIME
COMPONENT CHARGING TIME
Earbuds Up to 1 hour

Charging case Up to 3 hours
NOTES:
• When the earbud baery level is low, a 10-minute charge with the case closed
powers the earbuds for up to 2 hours.
2
• When the earbuds are fully charged, they can play audio for up to 7.5 hours with
immersive audio set to O (up to 4.5 hours with immersive audio set to On).
3
• When the case is fully charged, it can provide up to an additional 19.5 hours of
audio playback with immersive audio set to O (up to an additional 12 hours with
immersive audio set to On).
4
• When both the earbuds and case are fully charged, the total audio playback time
is up to 27 hours with immersive audio set to O (up to 16.5 hours with immersive
audio set to On).
5
• When fully charged, the earbuds can stay connected to a device while not playing
audio for up to 48 hours.
6
• When the earbuds are inside of the case, the case charging time varies.
1 Testing conducted by Bose in October 2023 using production-representative Bose Ultra Open Earbuds and Bose Ultra Open
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 10 minutes, then resuming Bluetooth A2DP audio playback with
volume set to a loudness of 75 dBA, 3-band EQ set to zero, and Immersive Audio o, resulting in up to 2 hours of 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.
2 See 1.
3 Testing conducted by Bose in October 2023 using production-representative Bose Ultra Open Earbuds playing IEC 60268-1
pink noise using A2DP Bluetooth audio streaming at an RSSI of 75 dBm. Volume was set to a playback loudness of 75 dBA
and 3-band EQ was set to zero. With Immersive Audio o, playback time was up to 7.5 hours before baery depletion. With
Immersive Audio on, playback time was up to 4.5 hours before baery depletion. Baery life varies based on seings
and usage.
4 Testing conducted by Bose in October 2023 by inserting production-representative Bose Ultra Open Earbuds with baery
depleted (to the point of no audio playback) into a fully charged Bose Ultra Open Earbuds charging case and charging earbuds
to 100% (or until the case baery was depleted). Then, the earbuds played IEC 60268-1 pink noise using A2DP Bluetooth audio
streaming at an RSSI of 75 dBm until baery depletion. Volume was set to a playback loudness of 75 dBA and 3-band EQ
was set to zero. Testing repeated until the case baery was depleted. Additional earbud playback time added through case
charging was 19.5 hours with Immersive Audio o and 12 hours with Immersive Audio on.
5 See 4.
6 Testing conducted by Bose in October 2023 by removing fully charged production-representative Bose Ultra Open Earbuds
from a Bose Ultra Open Earbuds charging case, connecting to a phone with no content playing, and maintaining connection
