• True Beryllium diaphgram for extended high frequency response and low distortion

• Frequency Response: 12 Hz to 45 kHz / Impedance: 32 Ohms nominal / Sensitivity: 100 dB SPL at 1 mW in ear / Power Handling: 20 mW continuous / THD: Less that 1% THD at 1 mW

• All components inside our IEMs was 100% designed and tooled in-house, resulting a totally unique product

• Beryllium is among the least dense stable metals, but also has among the highest Young's modulus values (a ratio of the stiffness) and speed of sound. This results in high efficiency and extremely low distortion as the diaphragm does not bend on its own, moves homogeneously, and dissipates internal energy very well

• We manufacture our own earbuds from medical grade silicones and urethanes, and we include small, medium, and large sizes of single flange, dual flange and foam units
