Cleaning
Get into the habit of regularly cleaning the product to ensure that it lasts for a long time. Do not use alcohol, paint thinners,
or other solvents for cleaning purposes.
Main unit
• When cleaning the main unit, remove the eartips.
• If the product becomes soiled with sweat or dirt, wash it away with fresh water at room temperature (10 to 35°C (50
to 95°F)), or weak running water, instead of using soapy water.
• Position the product so that the outer surface is facing the water flow (see figure below), and avoid pouring water
directly on the sound reproduction part, which is not water-resistant.
• Be sure to wash the product with your hands instead of using a brush or sponge.
• This product is waterproof to the IPX5 level, but the sound reproduction part is not water-resistant. Infiltration of
water into the inside of headphones may cause the product to make no sound or make the sound hard to hear.
• Natural oils from the skin are particularly likely to build up on the areas where the eartips attach to the headphones
(see figure below). If these areas are not cleaned, the eartips can become detached. Clean them regularly. Do not
touch the areas where sound is produced as they are delicate. Doing so may result in malfunction.
Direction of water flow
Eartip attachment part
Microphone
Sound reproduction part
(not water-resistant area)
After washing, wipe the product clean following the steps listed below:
1. Wipe off the water from the surfaces with a dry, clean cloth.
2. Hold the product firmly, and shake off the water about 20 times until no
drops of water sprinkle off.
• Moisture left in the sound reproduction part and microphones may
cause the product to make no sound. If that is the case, lay out a dry
cloth and shake both the sound reproduction part and the microphones
downward toward the cloth about 20 times each.
3. If water is left in a space between the sound reproduction part and
microphone, press a dry, clean and soft cloth gently to the product to wipe
off the moisture.
4. Dry them thoroughly in the well-ventilated shade.
• Do not apply hot air from a dryer directly onto the product.
• Do not use a cotton swab to forcibly wipe off the moisture left in a space between the parts of the product.
11
Cleaning
Cable and eartips
• Wipe away any perspiration or dirt from the cable with a dry cloth immediately after use. Failure to clean the cable
may cause it to deteriorate and harden over time, resulting in malfunction.
• Wipe the cable's USB plug with a dry cloth if dirty.
• Clean the eartips by removing them from the headphones and manually cleaning them with a diluted mild detergent.
After cleaning, dry before using again.
• If the product will not be used for an extended period of time, store it in a well-ventilated place free from high
temperatures and humidity.
Eartips
Eartip size
The product includes eartips in 4 sizes (XS, S, M, and L), and ridged eartips in 3 sizes (S, M, and L). At the time of
purchase, the M-size eartips are attached. To ensure the best sound quality, select the eartip size that is best suited for
you, and adjust the eartips inside your ears for a snug fit. It may be difficult to hear bass sounds if the eartips do not fit
snugly in your ears.
Replacing the eartips
Remove the old eartip and attach the new eartip by pushing it onto the
headphone at an angle (see figure).
Push firmly on the eartip so that the inside of the eartip expands, and push the
eartip onto the post as far as it will go.
• The eartips are designed to be difficult to remove, therefore the fit is very tight
when attaching them.
• Periodically remove and clean the eartips as they become dirty easily. Using dirty eartips may cause the
headphones themselves to become dirty, resulting in deteriorated sound quality.
• Eartips are consumable parts that degrade through storage and use. If the eartips are loose and easily removed or
if they appear to have degraded, purchase replacements.
• When reattaching eartips that were previously removed, be sure to check that they are securely attached. Injury
or illness may occur if the eartips become detached and are left inside the ear.
