EJ07 is equipped with a 10mm nano-carbon membrane dynamic driver, dual Sonion 2389 balanced armature mid-woofer and quad Sonion EST65QB02 electrostatic drivers. The ensemble is orchestrated by a meticulously tuned three-way crossover for low distortion and tangible treble.
The EJ07 shell is made out of the same medical grade resin that is used for prosthetics or hearing aids in the EU.The shells went through a strong ultraviolet exposure and longer treatment time to ensure such durability, comfort and lifespan of the unit. The thicker shells also provide a more isolating seal in the ear to block out up to 26dB of outside noise.
Stock cable included is a light-weight balanced 6N OCC copper cable, housed in a Nylon braid for added strength, RF rejection and minimal microphonics. If and when you feel like the upgrade bug bit you hard, the standard 0.78mm dual pin receptor allows for easy third party cable upgrade.
