Auto Volume

The earbuds can automatically adjust audio volume depending on the level of

noise around you. This helps your audio stay at a consistent volume relative to

your surroundings.

When Auto Volume is enabled and the noise level increases above your baseline

volume seing, audio volume increases proportionally after a few seconds. When the

noise level decreases, audio volume returns to your baseline seing.

• When you make or receive a phone call, Auto Volume is temporarily disabled. When

you end the call, Auto Volume returns to its previous seing.

Enable Auto Volume

Auto Volume is disabled by default. To enable Auto Volume, use the Bose app. You can

access this option from the Seings menu.

Manually adjust volume when Auto Volume is enabled

To manually adjust volume, use the earbud controls (see “Volume functions”) or the

volume controls on your device until you hear the volume change.

NOTE: If the earbuds are actively increasing audio volume due to noise, manually

adjusting volume may have a minimal or only temporary eect unless you

Immersive Audio takes what you're hearing out of your head and places it in front of

you—like you're always in the acoustic sweet spot. 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

beer sound clarity and richer sound quality.

NOTE: When you make or receive a phone call, Immersive Audio is temporarily set to

O (see page 22).

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 baery 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 and Auto Volume o, resulting in up to 2

hours of playback time before baery depletion. Time to achieve fully charged earbuds was determined by inserting earbuds

with baery depleted (to the point of no audio playback) into a fully charged case and charging earbuds to 100%

baery charge.

3 Testing conducted by Bose in January 2024 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 and Auto Volume o, playback time was up to 7.5 hours before baery

depletion. With either Immersive Audio or Auto Volume on, playback time was up to 4.5 hours before baery depletion. With

both Immersive Audio and Auto Volume on, playback time was up to 3.5 hours before baery depletion. Baery life varies

based on seings and usage.

4 Testing conducted by Bose in January 2024 by inserting production-representative Bose Ultra Open Earbuds with baery

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 baery was depleted). Then, the earbuds played IEC 60268-1 pink noise using A2DP Bluetooth audio

streaming at an RSSI of 75 dBm until baery depletion. Volume was set to a playback loudness of 75 dBA and 3-band EQ

was set to zero. Testing repeated until the case baery was depleted. Additional earbud playback time added through case

charging was up to 19.5 hours with Immersive Audio and Auto Volume o, up to 12 hours with either Immersive Audio or Auto

Volume on, and up to 9 hours with both Immersive Audio and Auto Volume on.

SYMPTOM SOLUTION

Adjusting volume has

minimal effect while

Auto Volume is enabled

If the earbuds are actively increasing audio volume due to noise,

manually adjusting volume may have a minimal or only temporary

eect unless you increase the baseline seing above the

current level. To increase the volume in this situation, keep

increasing the volume using the earbud controls or your device

controls until you hear the volume change (see page 18). To

decrease the volume, disable Auto Volume using the Bose app,

then decrease the volume (see page 18).

Audio gets louder when

you talk while Auto

Volume is enabled

Auto Volume is designed to disregard your voice as much as

possible when measuring the level of noise around you. If you

notice audio geing louder when you talk, the earbuds may be

angled too far downwards towards your mouth or chin. Check the

earbud fit using a mirror (see page 14). For best sound quality

and microphone performance, adjust the earbuds so that they’re

at about a 45° angle on your ears. If they don’t feel comfortable

or secure, slide them up or down slightly to find the best position

for you.

Audio gets louder when

other people talk while

Auto Volume is enabled

Auto Volume categorizes other people's voices as environmental

noise, meaning that your audio volume may increase to

compensate for loud voices. To prevent this, you can either pause

audio during conversations (see page 17) or disable Auto

Volume using the Bose app. You can access this option in the

Seings menu.

Earbuds don’t charge

Make sure the earbuds are properly placed in the charging case.

To help preserve the baery life, the case should be closed while

the earbuds are charging (see page 25).

Make sure there is no dirt, debris, or liquid covering the charging

contacts on the earbuds or the charging pins in the case.

Remove the plastic film from the surface of the case under each

earbud to prevent it from interfering with earbud placement.

Make sure the USB cable is correctly aligned with the port on the

charging case.

Secure both ends of the USB cable.

Try another USB cable.

Try another wall charger.

If the earbuds or charging case have been exposed to high

or low temperatures, let the earbuds or case return to room

temperature. Charge again (see page 25).

Charging case

doesn’t charge

Make sure the USB cable is correctly aligned with the port on the

charging case.

If the charging case baery is fully depleted, make sure the

USB cable is aached long enough for the case to gain an initial

charge. If you remove the cable and the charging case status light

goes out, reaach the USB cable.

Secure both ends of the USB cable.

Try another USB cable.

Make sure the charging case is closed. To help preserve the

baery life, the case should be closed while it’s charging.

Try another wall charger.

If the charging case has been exposed to high or low

temperatures, let the case return to room temperature. Charge

again (see page 27).

If the charging case has been exposed to water, wait until the

USB-C port is completely dry. Charge again (see page 27).

Make sure any charging case accessories are properly installed

and don't prevent the USB cable from securely connecting to the

port on the charging case.

Earbud battery life is

shorter than expected

Baery life varies based on seings and usage. If either

Immersive Audio or Auto Volume are set to On, consider disabling

them using the Bose app for a longer baery life. For more

information, see page 29.
