situations where hearing must not be impaired,

for example, a railroad crossing, a construction

site, etc.

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

ordered from your nearest Sony dealer.
