STAY AWARE OF YOUR SURROUNDINGS
The sleepbuds™ are designed to mask noise and disturbances while you sleep.
Because of this, they can aect your ability to hear other sounds, such as alarms,
warning systems, people and pets.
SET AN APPROPRIATE VOLUME
To balance the levels of noise masking and awareness you want, set an appropriate
volume level for your needs. The volume should be high enough to mask noises that
are disturbing your sleep, but not so high that you can’t hear the sounds you want
to hear.
In the Bose Sleep app, set the volume to the lowest level, then increase it gradually
until you reach an appropriate level. The lower the volume, the more likely it is that
you’ll be able to hear the sounds you want or need to hear.
TIPS FOR MAINTAINING AWARENESS
If you’re concerned about your ability to hear sounds while wearing the sleepbuds™,
try the following tips.
Basic tips
• If you sleep with a partner, consider relying on your partner to help you stay aware
of your surroundings while wearing the sleepbuds™.
Advanced tips
These tips make the sleepbuds™ less eective at masking noise, but further increase
your awareness of your surroundings.
• Wear only one sleepbud™.
• Set your current masking sound so that it stops after a certain amount of time
instead of playing all night. You can do this by setting a sleep timer for your current
masking sound in the Bose Sleep app.
