Product ID: 01523
Upgraded SF driver, which is main part of INFINITY ARD (Advanced Research Driver), produced stronger diaphragm by ’46 nano / 3 multi-layers’ method, provides minimum partial vibration with shape of diaphragm through scientific 3D scanned analysis.
Product’s Color:

The Ideal Multi-Layer Driver Technology In The World

INFINITY ARD (Advanced Research Driver) is based on
Professor Shin-Ryeol Lee’s SF Driver,

which is upgraded and designed for structure of AZLA Horizon and overall sound flow.

Infinity Advanced Research Driver

SF(Superior Fidelity) Driver: Developed by Professor Shin-Ryeol Lee, the next generation’s driver which removes partial vibration at the driver, enables to play original sound.
Upgraded SF driver, which is main part of INFINITY ARD,
produced stronger diaphragm by ’46nanos 3multi-layers’ method, provides minimum partial vibration with shape of diaphragm through scientific 3D scanned analysis.

Characteristics of Sound

The special thing is, fundamentally closes phase distortion due to whole sounds are made from one diaphragm without crossover network.
Throughout scientific diaphragm analysis, there is able to minimize partial vibration, therefore it is able to play super high frequency range which is over 30kHz area, and minimized phase distortion and frequency characteristics through sole diaphragm, it was unable to reduce with common earphones structure.
Especially, by adding ‘Air Flow’ technology, 

which is system of Infinity Driver for AZLA,
minimized sound distortion and improves staging, space impression and sense of hitting.
In summary, main advantage is to be able to realize natural acoustic atmosphere
and sense of hitting though bass range.

Sound Air Vent Holes

HORIZON is, engraft Air Flow technology which is used for AZLA-01R,
improves space impression and staging sense.
For clearer and deeper sound, applied two holes with Air Flow technology
to the metal housing, it finishes INFINITY ARD and provides
very special hitting sense, deep and rich bass and specialized wide staging.
Through Horizon, able to enjoy natural sound and concrete low sound,
never experienced before with conventional earphones.

Drawing For Best Sound Quality

Horizon’s design has been started to make earphone as a speaker.

For ‘space’, like as loudspeaker, AZLA researched hard and finally found the best design to apply to the production. Material also, after numberless
of trials and errors, top grade of polycarbonate housing is chosen and
combined with metal housing.
Assembly method of AZLA Horizon is patent pending method, it is completely new.
Regarding assemble different materials, applied ‘sound prefer’ method.
Minimized chemical assemble way (bonding), and best sound is provided through screw-finished way, of course whole parts are fixed well.
Horizon is, applied the best shape for the best fitting at human ears
throughout many modeling and test, after that the user able to enjoy the best sound
with the best and stable fit.

Cable For Superior Sound

AZLA fully understands that cable is extremely important.
Therefore, researched and developed the best cable through long time, and finally succeeded to apply the result to Horizon.
Urethane-coated high-quality copper wires are built with 128 strands total (32 copper wire, Kevlar/250D*4 cores),

present accurate sound with low impedance
through various treatments.
Also, applied superior cable weaving method, which is using for high-end earphones only, and finished 4wires cable weaving for L/R, after that, able to experience the quality sound.

Removal MMCX is using for Horizon.
Stable and high quality MMCX from Delta Electronics in the US,
provides stable quality.
Eartips Throughout Listening Music

Supplying SEDNA eartips, developed and designed by AZLA.

SEDNA eartips is made in Korea, by high-quality silicone
for special purpose, not common silicone.
Provides outstanding fit and presents perfect sound from Horizon.
