Cleaning
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.
• To clean, wipe with a dry cloth.
• Immediately wipe off any moisture such as sweat that enters the battery jack. Failure
to do so may result in a malfunction due to corrosion.
• Natural oils from the skin are particularly likely to build up on the eartip attachment
parts (see figure at right). 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.
• 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 silicone eartips in 4 sizes (XS, S, M, and L). At the time of purchase, the M-size silicone 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.
