It feels like the sound is coming from outside the earbuds, resulting in a more natural listening experience. Immersive audio works on any streaming content from any source, taking it to new heights with better sound clarity and richer sound quality.
NOTE: When you make or receive a phone call, immersive audio is temporarily set to Off (see page 22).

· 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 battery 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 off, resulting in up to 2 hours of playback time before battery depletion. Time to achieve fully charged earbuds was determined by inserting earbuds with battery depleted (to the point of no audio playback) into a fully charged case and charging earbuds to 100% battery charge.

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 off, playback time was up to 7.5 hours before battery depletion. With Immersive Audio on, playback time was up to 4.5 hours before battery depletion. Battery life varies based on settings and usage.
4 Testing conducted by Bose in October 2023 by inserting production- representative Bose Ultra Open Earbuds with battery 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 battery was depleted). Then, the earbuds played IEC 60268-1 pink noise using A2DP Bluetooth audio streaming at an RSSI of 75 dBm until battery depletion. Volume was set to a playback loudness of 75 dBA and 3-band EQ was set to zero. Testing repeated until the case battery was depleted. Additional earbud playback time added through case charging was 19.5 hours with Immersive Audio off and 12 hours with Immersive Audio on.
