M12 · Start Your Mobile Hi-Fi Journey
To greet mobile lossless music in the 5G era, Questyle released the M12 in 2021, a mobile Hi-Fi headphone amplifier with DAC, which integrates
Questyle’s core technology and carries on the gene of mobile Hi-Fi feature. M12 allows all mobile phone users to break through limitations of technology, cost and size of the audio circuit integrated into mobile phones, and feel free to enjoy lossless music from streaming anytime in any place.
Smart Detection of Impedance Automatically self-adjust to fit your headphones
When M12 is plugged into a headphone, the built-in smart detection system will start automatically to detect the headphone impedance and self-adjust to
fit the headphone. Just like the auto shift of a car, M12 will self-adjust to high power level to drive high-impedance headphones with the Gain indicator showing red light, providing excellent dynamic performance. When driving low-impedance and high-sensitivity earphones, M12 will reduce the output level and accurately match their impedance, with the Gain indicator showing green light for low impedance.
