INTRODUCTION
Molex is pleased to announce our entry into the audio
accessories market with our new line of Evaldi™
earphones. These noise-isolating earphones offer high
fidelity sound quality and a comfortable fit.
The new Evaldi™ earphones from Molex aim to provide
“3-Dimensional” sound that is equivalent to listening to
a set of high-end home stereo speakers. The secret is in
our patented airstream-control technologies that enable
the transmission of both sharper high tones and lower
bass sounds without interference.
The Evaldi™ line also provides superior comfort and ways
to customize your sound experience. An inclined stem
with elliptical shape is employed to better fit ear canals,
while a choice of ear pads provides users different levels
of bass and noise isolation.
