Evaldi™ Earphones
With Airstream Features
for Superior Sound Control
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.
Specifications:
■ Style: Canal-type
■ Driver Unit: 13.5mm
■ Power Handling Capacity: 50mW
■ Impedance: 16 Ohms at 1kHz
■ Frequency Response: 20Hz to 20kHz
■ Cable Style: Y -type
■ Cable Length: 1,200mm
■ Plug Type: 3.5mm diameter (1/8”)
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.
THE EVALDI™ DIFFERENCE: “3D” SOUND
Patented technologies control the airstream to provide a wider and more stable sound experience
Exit shape with grooves
creates a stable air channel
Precision-shaped pressure
ring can be customized to
achieve desired frequency
tones
Different size exhaust
holes provide additional
frequency controls
Evaldi™ canal-type earphones (top) replicate the sound experience of listening to external speakers
from a 45-degree (middle) or 90-degree angle (bottom)
SOUND-CUSTOMIZING EAR PADS
Two types of ear pads are provided to let users customize
their sound preference. The Open type includes a center
hole surrounded by six smaller elongated holes. This design protects against any low frequency boosts of sound
and absorbs any external noise for a more balanced listening experience. The Closed type of ear pad (top) provides more isolated bass
sounds, while Open type
(bottom) helps balance out
high and low tones better.

COMFORT FITTING
University laboratory studies of the human ear canal conducted in the
development of the Evaldi™ earphones helped lead to the creation of original
ear entry tube and ear pads.
Inclined stem design provides a more comfortable fit. Ear pads are made of thin,
soft cushion-style rubber material to add to comfort over long periods of use.
For better in-ear fit, an ellipse
stem shape is employed.
CHOICE OF EAR PADS
The Evaldi™ earphone system includes six sets of ear pads: small, medium and large in both Open and Closed types.
This allows users to customize their listening experience even further.
Closed Type (L: 2pcs / M: 2pcs / S: 2pcs)
When assembling the Open-type ear pad, the grooves on the stem should
be aligned with the vents in the ear pad to help create a stable air channel.
