CHANGING

FILTERS

Etymotic

earphones

have

special

filters

that

smooth

the

frequency

response

and

prevent

earwax

from

entering

the

earphones

. A

filter

is

located

at

the

end

of

the

earphone

and

is

visible

when

the

eartip

is

removed.

If

a

filter

becomes

clogged,

it

should

be

replaced.

A

dirty

filter

will

reduce

earphone

output.

The

filter

should

be

changed

if

loudness

decreases

or

the

sound

quality

declines.

Note:

Filters

are

not

reusable.
