Note
As the earbud tips fit more snugly in your ears, you may feel a strain to your ears. If you experience discomfort, discontinue use.
Do not pull on the polyurethane foam portion of the earbud tip. If it is separated from the earbud tip, it will not function.
Do not subject the polyurethane foam portion of the earbud tip to pressure for over long periods of time. It may cause deformation
and it may be difficult to return the earbud tip to the original shape.
When the earbud tips become dirty, do not wash them in water, but wipe off the dirt using a dry cloth. Do not use alcohol, etc.
Doing so may quicken the deterioration.
When the earbud tips get soaked, drain the liquid well, and make sure that the earbud tips are dried before use or storage.
The foam materials used in the earbud tips deteriorate through long-term use and storage. Replace the earbud tips if the
deterioration results in reduced performance.
The varying sizes of the holes on the polyurethane foam portion of the earbud tip have no effect on the sound quality.
You may hear a cracking noise in your ears when wearing the headset, but this is not a malfunction.
The foam materials may become firm at a low temperature. Warm the earbud tips a little with your hands before use.
When the environmental temperature or usage temperature is high, the polyurethane foam may take time to return to its original
shape.
If you feel that the bass sound has become insufficient (or that the sound quality has deteriorated), exchange the earbud tips with
new ones.
