We tried countless times using metal plated diaphragms of magnesium, titanium, and beryllium plating with different suspensions and with many different tuning materials. Finally we chose plating each side of the driver with beryllium of the IT01X. The density of beryllium is only 1/2 of that to be drive with ease. The double-sided beryllium-plated diaphragm has outstanding rigidity, quick response with extremely low distortion, smaller internal resistance, wider high frequency bandwidth, and better overall treble extension.
A Dual Helmholtz resonator driver provides deep and powerful bass that prohibits standing waves and ensures full natural sound.
The IT01X utilizes a 3D (three-dimensional) suspension. It can effectively inhibit the divided vibration of the driver, reduce the distortion, and further improve the sound purity.

Highs are great; mids are average; bass is poor; these IEM's need tips with an EXACT fit and a good seal. The tips supplied are trash. Cable gets tangled easily. It might be my ears but these don't fit well generally.
