• To prevent rusting, regularly clean the charging contacts on the earbuds with a dry,

soft cotton swab or equivalent.

• IPX4 is not a permanent condition, and resistance might decrease as a result of

normal wear.

ENG

HOW TO WEAR

INSERT THE EARBUDS

1. Insert the earbud so the eartip gently rests at the opening of your ear canal.

NOTE: Each eartip is marked with either an L (left) or an R (right).

2. Slightly rotate the earbud back until the eartip creates a comfortable seal at

your ear canal.

NOTE: Rotating the earbud too far back (or forward) may impact audio and

microphone sound quality.

3. Tuck the top of the eartip wing under your ear ridge.

Insert Rotate Tuck

ENG

HOW TO WEAR

CHECK YOUR FIT

Use a mirror to make sure you have successfully rotated the earbud back, tucked the

eartip wing, and that you’re using the best eartip size for each ear.

FIT WHAT TO CHECK

Proper ﬁt

When the eartip ﬁts properly:

• The eartip gently rests at the opening of your ear

canal to create a comfortable seal. Background

noise should sound mued.

NOTE: Noise cancellation may impact the ability

to hear mued noise.

• The eartip wing doesn’t stick out or feel squished

under your ear ridge.

Too big
