We Want You Listening For A Lifetime
YAMAHA and the Electronic Industries Association's
Consumer Electronics Group want you to get the most out of
your equipment by playing it at a safe level.
One that lets the sound come through loud
and clear without annoying blaring or
distortion – and, most importantly, without
affecting your sensitive hearing. Since
hearing damage from loud sounds is often
undetectable until it is too late, YAMAHA and
the Electronic Industries Association's
Consumer Electronics Group recommend
you avoid prolonged exposure to excessive
volume levels.
