Three Balanced armature drivers
What are balanced armature drivers?
In a nutshell, balanced armature drivers use a signal to vibrate a small reed balanced between two magnets. The motion of the reed is transferred onto a stiff diaphragm, free of resonance, allowing it to deliver exceptional clarity. The design engineers at 1MORE have packed three of our patented armature drivers into the mighty Quad. Calibrated to approach a wide auditory spectrum, they interact to render precise, bright highs and a sharply responsive mid range. The output is marked by an oaken warmth and lucid instrument separation, for every kind of music.

The Cutting Edge
Graphene Composite Diaphragm
Graphene is a one-atom-thick layer of carbon atoms arranged in a hexagonal lattice. It is the thinnest, lightest and toughest material known to man and is extraordinarily conductive. At 1MORE's Research Labs, we've been busy designing better diaphragms for our earphones. The Quad Driver packs a pair of 1MORE's patented graphene composite diaphragms - a layer of graphene with two layers of PET. Due to its low mass density, it delivers outstanding frequency response across the entire audible spectrum (20 Hz~40 KHz). The softer PET drives thundering bass and low mid, while the light and unyielding graphene adds a crispness and space to the mid and high frequencies that is, with deliberate disregard for a better word, delicious.


Comfort, ergonomics and sonic balance
Designed to perfection
Streamlined aluminium sound chambers with tungsten textured accents flow like a jet engine, yet are designed for premium comfort and sonic spaciousness while eliminating ear fatigue. The oblique angles of these earphones align with the natural curve of your ears. Moreover, the snug fit from our nine included Quad Tips (6 silicone, 3 foam) increases noise isolation, fullness and clarity for a more intimate sound stage. 1MORE's commitment to a naturally balanced sound, without the harsh bass and treble boosting prevalent in some earphones, presents a satisfying listening experience, even at healthy volume levels.
SMART CONNECT
Seamless music control
Intelligently designed, the sleek and slender controller identifies devices instantaneously! Automatically connects to your smartphone or tablet; providing access to adjust volume, shuffle through songs and make calls. The wired remote comes with 3 buttons made of metal having a tactile and clicky feel that help you navigate music and calls. The superior MEMS microphone delivers exceptional talk quality.
