Prolonged use of the noise isolation earbuds may strain your ears due to their snug fit. If you have  
Earbud  
experience discomfort or pain in your ears, discontinue use.  
The pressure-relieving urethane cushion is extremely soft. Therefore, do not pinch or pull the  
urethane cushion. If the urethane cushion is broken or detached from the earbuds, it will not take its  
correct position and the earbuds will lose their noise isolation function.  
The pressure-relieving urethane cushion may deteriorate due to long-term storage or use. If the  
pressure-relieving power is lost and the urethane cushion becomes hard, the earbuds may lose their  
noise isolation function.  
Do not wash the noise isolation earbuds. Keep them dry, and avoid accumulation of water in the  
pressure-relieving urethane-cushions. Not doing so may cause early deterioration.  
Tactile dot  
To detach an earbud (see fig. -)  
While holding the headphone, twist the parts inside of the earbud and pull the earbud off.  
Tip  
If the earbud slips and cannot be detached, wrap it in a dry soft cloth.  
To attach an earbud (see fig. -)  
Push the parts inside of the earbud into the headphone until the projecting part of the  
headphone is fully covered.

of static electricity accumulated in the body, and not a malfunction of the headphones.  
The effect can be minimized by wearing clothes made from natural materials.
