MAINTENANCE

It is important to periodically clean the ear tips and bodies of

Master & Dynamic earphones, as well as the acoustic filter found

at the end of each earphone body. Doing so will help ensure

consistent audio performance. Even small amounts of debris,

dirt and wax can dramatically reduce or eliminate sound output.

To clean the acoustic filter, follow these steps:

Remove the tips from the

earphone bodies;

Remove acoustic filter by

turning counter clockwise;

Fully submerge acoustic

filter in hydrogen peroxide

for a few minutes to allow

the debris, dirt or wax to

loosen;

Apply hydrogen peroxide to a

clean cotton swab or soft cloth

to gently scrub the acoustic

mesh. Let dry completely;

To clean the ear tips, wipe using

mild soap or isopropyl alcohol.
