HOW TO WEAR

15

|

ENG

CHECK YOUR FIT

For the best fit, audio performance, and noise cancellation, use a mirror to make sure

you’re using the correct size eartips and stability bands. You may need to try a

dierent size eartip or stability band for each ear.

TIP: You can also check your fit using the Earbud Seal Test in the Bose Music app. You

can access this option from the Seings menu.

Eartips

FIT WHAT TO CHECK

Proper fit

The eartip gently rests at the opening of

your ear canal to create a comfortable seal.

Background noise should sound muled.

NOTE: Noise cancellation may impact the

ability to hear muled noise.

Too much pressure The eartip feels uncomfortable and

squished in your ear canal.

Too loose

The eartip rests too deep in your ear canal,

feels loose in your ear, or falls out when you

move your head.

ENG

TRY ANOTHER SIZE

Wear the earbuds for an extended period of time. If the earbuds don’t feel

comfortable or secure, or noise cancellation or sound quality isn’t as expected, try

another size eartip or stability band.

You may need to try all three eartip or band sizes or use a dierent size eartip or band

for each ear.

Eartips

Three sizes of eartips are included with the earbuds: small, medium, and large.

Medium eartips come aached to the earbuds. If they feel too small, try large eartips.

If they feel too big, try small eartips.

Stability bands

The stability bands are marked with size 1 (small), 2 (medium), or 3 (large) and an R

(right) or L (left).
