UNDERSTANDING THE PRODUCT
SPECIFICATION
Sound pressure, Decibel and Hz
Sound is an invisible vibration composed of
frequencies which travel in undulations known
as sound waves. The amplitude of vibration pro-
duced by an object such as a speaker driver is
proportional to the change of pressure generated
as the wave moves through the medium which
surrounds it (such as air). Therefore, the ampli-
tude of a sound wave is commonly measured by
its pressure level.
The decibel is a non-dimensional, logarithmic
scale to denote a relative change in the strength
of a signal or wave. When placed in the context
of sound pressure level; it measures the nominal
threshold of human hearing, relative to the
quietest sound audible to the human ear.
The frequency of instances where a sound
wave reaches it peak during a period of time is
measured in Hz (hertz). This is the number of
complete cycles per second. Human hearing is
limited to frequencies between about 20 Hz and
20,000 Hz.
Sensitivity and impedance
Earphone sensitivity is measured in Sound
Pressure Level (SPL). This is essentially a
measurement of how loud or easily-driven a pair
of earphones are.
The sensitivity is also influenced by the drivers'
coil impedance which varies over the frequency
range. The higher the SPL and the lower the im-
pedance the more easily driven your earphones
will be.
PRECAUTIONS
• Do not use the product in other ways than
are described in this manual.
• Handle with care at all times and protect
from external damage.
• Do not expose to heat, magnetism or cold,
damp environments.
• To clean: use a mild, antiseptic detergent.
• Do not expose the cables and plugs to
abnormal wear and tear, e.g. by bending or
pulling them.
• Avoid winding the cable too tightly.
• Avoid dropping or strong impact.
• Always leave the sleeve on for shock
protection.

PROPER USE

The a-JAYS Five earphone model is suitable for
many different areas of use. It is particularly
suited to environments where you are likely to be
disturbed by ambient noise, e.g. at airplanes, on
trains, on the subway, at the gym or when you are
studying. In short, whenever you want. Let noth-
ing come between you and the full enjoyment of
your music.
Inserting and removing the earphones
• Turn the volume to minimum before
insertion.
• For best results, moisten the sleeves before
insertion.
• Holding the earphone at the rear, carefully
insert the sleeve while pulling up and out
on the back of the ear.
• The earphone should seal deeply and
comfortably in the ear canal.
• If the bass frequency response seems too
feeble or if external noise has not been
eliminated, try inserting the earphone
deeper into the ear canal to obtain a better
seal or try a different sleeve size.
• After use, remove carefully - avoid pulling
the cable.
