【Two Years of Outcome】

Music is the eye of the ear. With two years of dedicated research and adjustment,  HarmonicDyne Devil eventually comes in time so as to provide a earphone of surprisingly acoustic performance and high artistic value for the audiophile community. Featuring two flagship custom 10mm dynamic drivers, HarmonicDyne Devil sound performance is proved to be above the majority particularly in deep bass, powerful treble and clean highs.


Dual 10mm Dynamic Driver

Devil adopts high precision CNC magnet circuit system with superstrong NdFeB to achieve Tesla-grade flux. 16 ohms low impedance and Japanese imported CCAW voice coil make it easier to use on daily devices, such as phone. Self-developed LDM membrane material is lightweight and rigid that also contributes to the improvement of frequency response speed and transient changes.


Balanced Natural Fine Tuning

The tuning signature of Devil is overall natural and balanced with ultra-low distortion and pleasant smoothness. With careful tuning process, Devil brings powerful performance without overly prominent harshness or lack of certain frequency bands that produce spaced disconnects, which means that Devil must meticulously deliver every tiny detail in the music. Excellent frequency response makes it possible to reveal each tiny changes of emotion in a song, bringing you a more realistic and moving listening experience.


Detachable Coaxial OCC Cable

Devil includes a well made coaxial OCC cable, consisting of 33*0.08mm  and 38*0.06mm strands. Special structural design provides purer and clearer sound performance. Moreover, a PVC insulation layer is added to ensures excellent electrical insulating while suspension layer is covered with high-density Nylon to avoid microphonics. Less interfere, more joy


【Aviation-gradeCNC Aluminum Alloy Shell

The housing of the Devil is designed after a large number of simulation experiments to match the typical ear angle and wearing experience. Each unit is crafted from a high-precision 5-axis CNC to ensure uniformity of the acoustic chambers. Selected aviation-grade Aluminum alloy is lightweight and rigid to stand everyday wear-and-tear. From the housing design to the driver assembly, each aspect of the Devil is a demonstration of workmanship, engineering prowess, and acoustic tastefulness.
