The Apollo utilizes Sendy Audio's Quad Former technology, meaning that each side of the diaphragm has dual sided magnets, giving a total of 4 magnets per diaphragm. This gives impressive control over the motion of the driver, and thus greatly improves the accuracy of the sound. The result is a very efficient and consistent driver with extremely low distortion.
More than three years of experimentation with planar drivers means the 68mm diaphram is extremely capable, with a frequency response of 20Hz-40kHz, and an SPL rating of 95db.
The high quality rosewood ear cups can be adjusted both horizontally or vertically, making it easy to get the proper fit. The Sunburst design on the steel end caps not only looks smart, but each hole is carefully CNC machined to tune the overall sound character.
The goatskin headband pad and steel spring style headband make the headphones light and non fatiguing to wear.
The earpad is made of high protein materials and memory form, which is soft and comfortable. The pad goes all the way around the ear, so there's no pressure on the ear itself.
6N OCC braided cable ensure no signal loss during transmission. The detachable cable is suitable for upgrading.
The cable is with slant design on the headphone housing, which is beautiful and ensures the cable not to fall on the shoulder when wearing the headphone.
