As headphones reduce outside sounds, they may
cause a traffic accident. Also, avoid listening with
your headphones in situations where hearing must
not be impaired, for example, a railroad crossing, a
construction site, etc.
Note on static electricity
In particularly dry air conditions, noise or sound
skipping may occur, or mild tingling may be felt on your
ears. This is a result 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.
