How do I know that I have the
headphone tips in my ears correctly
with a proper fit?
The headphones come with three sizes of soft StayHear
®
+ tips. To ensure
proper headphone performance, it is important that you find the
appropriate tip size for your ear.
You should experiment with the different sizes of tips and assess the
comfort and noise reduction performance of each. As a quick test, put
both tips in your ears and speak aloud (with the headphone power off).
Your voice should sound loud, yet muffled (as if your fingers were blocking
your ears). Test until you find the size that best suits your ear size and gives
you proper performance.
Can I wash the StayHear
®
+ tips? Will my
StayHear+ tips change color or get dirty
over time?
The StayHear
®
+ tips are made of a durable material that can be washed
with a mild detergent and water, and dried as needed. Allow the ear tips
to dry completely before reattaching them to the headset.
The StayHear+ tips should be very resistant to dirt or the effects of UV
radiation, which typically cause some color change. With normal use, the
appearance of the tips should remain unchanged through years of use.
Are the StayHear
®
+ tips compatible with
other Bose
®
in-ear headphones?
No. The StayHear
®
+ tips are not compatible with other Bose
®
in-ear
headphones. They have been designed so they cannot attach to other
in-ear headphones, to ensure proper performance of each headphone
model.
