Material: CNC machined aluminum Color: Black / Silver Size: 51[L] X 16.5[W] X 8.1[D] (mm)
Operating System Required: Android phone and pad: Android 5.0 and above PC: Win10 1803 and above Apple cellphone: iOS (You need to buy an OTG cable for Lightning to Type-C.) Apple computer: Mac OS
Frequency Response: ±0.1dB(20Hz-20kHz) THD+N: 0.0003% DAC: ESS flagship USB DAC chip ES9281AC
Output Power: Built-in smart detection circuit will automatically self-adjust the output power to fit different impedance of headphones. RL=16Ω，Po=46.11mW; RL=32Ω，Po=26.71mW; RL=300Ω，Po=12.26mW; When the detected impedance is less than 70Ω, M12 will self-adjust to low gain output. When it is more than 70Ω, M12 will self-adjust to high gain output. When it is more than 600Ω, M12 will automatically switch to 2Vrms line out.
