Notes on use
⁃
To ensure compatibility and correct usage,
always consult the user manual of any device
before connecting the product to it.
⁃
Audio-Technica will not be liable in any way for
any loss of data in the unlikely event that such
losses should occur while using the product.
⁃
On public transport systems or in other public
places, keep the volume low so as not to
disturb other people.
⁃
Minimize the volume on your audio device
before connecting the product in order to avoid
hearing damage from sudden exposure to
excessive volume.
⁃
When using the product in a dry environment,
you may feel a tingling sensation in your ears.
This is caused by static electricity accumulated
on your body, not by product malfunction.
⁃
Do not subject the product to strong impact.
⁃
Do not store the product under direct sunlight,
near heating devices or in a hot, humid or dusty
place. Do not allow the product to get wet.
⁃
When the product is used for a long time, the
product may become discolored due to ultraviolet
light (especially direct sunlight) or wear.
⁃
The cable may become caught or severed if
the product is placed in a bag or pocket without
adequate protection. Always store the product
in the included case.
⁃
Connect/disconnect the cable by holding the
plug. Pulling directly on the cable can result in
a broken wire and the risk of electric shock.
⁃
Do not wind the cable around your portable audio
device. This may damage or sever the cable.
⁃
Do not use a cable other than the supplied
detachable cable.
⁃
Be sure to purchase the appropriate
conversion plug adaptor when connecting
the product to equipment with other than a
3.5 mm (1/8”) stereo headphone jack.
⁃
Lengthening the headphone cable requires a
separate extension cable available from your
dealer.
■
Care
Get into the habit of regularly cleaning the product
to ensure that it will last for a long time. Do not
use alcohol, paint thinners or other solvents for
cleaning purposes.
⁃
Use a dry cloth to clean the headphones.
Especially, the eartip contact area can easily
be soiled with earwax through the eartips.
Since dirt may cause the eartips to come off
easily, be sure to clean them regularly. Also,
do not allow the cloth to touch the area from
the sound producing area because it is more
susceptible to damage.
⁃
Use a dry cloth to clean the cable of any sweat
or dirt. Failure to clean the cable may cause it
to deteriorate and harden over time, resulting
in malfunction.
⁃
Wipe the plugs on the cable with a dry cloth
if dirty. Using the plugs without cleaning them
can cause sound interruption or distortion.
⁃
For long-time storage, keep the product
in a well-ventilated place without high
temperatures and humidity.
⁃
Refer to ''Cleaning the eartips'' in ''About the
eartips'' to learn how to clean the eartips.

Sound producing
area
⁃
Follow applicable laws regarding mobile

product while driving.
⁃
Do not use the product in places where the
inability to hear ambient sound presents a
serious risk (such as at railroad crossings,
train stations, and construction sites).

the volume to a level where you can still
hear background sound and monitor the area
around you while listening to music.
⁃
Store the eartips out of the reach of small
children.
⁃
If you begin to feel unwell while using the
product, discontinue use immediately.
⁃
To prevent damage to your hearing, do not
raise the volume too high. Listening to loud
sound for an extended period may cause
temporary or permanent hearing loss.
⁃
Discontinue use if skin irritation results from
direct contact with the product.
⁃
Do not disassemble, modify or attempt to
repair the product.
⁃
When removing the product from your ears,
check to make sure the eartips are still attached
to the main unit. If the eartips become lodged
in your ears and you are unable to remove
them, consult a physician at once.
