If you have in-ear earphones, you
need the EAP03, the ultimate accessory
for your portable music player. Portable
music players have earphone drive circuits
that are designed to limit the power in order
to conserve battery life, minimize space,
and minimize cost. This might be acceptable
if you plan to use their earbuds, but if
you've spent the money to buy the best
earphones, you're sure going to need more
than what your audio player will provide.

From the integrated microphone to the
sound-level meter function, this
instrument will change the way you
listen to your earphones. Click the

features of the EAP03.
