Dear Customer,
Thank you for choosing the JBL®brand. For more than 60 years, the
JBL brand has been
involved
in every facet of music and film recording and reproduction. From live performances to
monitoring the recordings you will soon play
in your home, office or home theater, the JBL brand
has provided a critical link.
As good as
JBL products already are, our high-fidelity research moves forward, resulting in new
products with even higher performance capabilities.
We are confident that the
JBL products you have chosen will provide every note of musical
enjoyment you expected -and that when you think about additional loudspeakers for your home
and your
car, you will once again choose JBL equipment.
Please take a moment to participate
in our survey at www.jbl.com in the product registration
section. This will enable us to keep you posted on our latest advancements, and will help us to
understand our customers better and to build products that meet their needs and expectations.
Thank you for selecting JBL equipment.
HARMAN International Industries, Incorporated
A message from the JBL manufacturer
and the Consumer Electronics Association:
Selecting fine audio equipment, such as the headphones you have just purchased, is only
the start
of your musical enjoyment. Now it is time to consider how you can maximize
the fun
and excitementyour equipment offers. The JBL manufacturer and the Consumer
Electronics Association wantyou to
get the most out of your equipment by using it at a
safe volume level, one that lets the sound come through loud
and clear, without annoying
blaring
or distortion -and, most important, without affecting your sensitive hearing.
Sound can be deceiving. Over time your hearing "comfort level" adapts to higher volumes of
sound. What sounds "normal" can actually be loud and harmful
to your hearing. Guard against
this by choosing a safe level BEFORE your hearing adapts.
TO ESTABLISH A SAFE LEVEL:
• Start your volume control at a low setting.
• Slowly increase the sound until you can hear it comfortably, clearly and without distortion.
ONCE YOU HAVE ESTABLISHED A COMFORTABLE SOUND LEVEL:
• Do not exceed that level.
fAn Taking a moment to do this now will help to prevent hearing damage or loss in the
~ future. After all, we want you listening for a lifetime.
