Its flexibility of use and the quality of its sound reproduction make it the ideal companion for your headphones or earphones.

Questyle M18i: Current Mode Amplification

Questyle's M18i features the brand's signature current-mode amplification technology. This innovative approach, developed by the brand's founder Wang Fengshuo, sets itself apart by processing the signal as a current rather than a voltage, and uses transistors within a fully discrete architecture operating in pure Class A to deliver the best possible output. This approach has many advantages, including a significant reduction in transient intermodulation distortion (TIMD), a much higher bandwidth and extremely low harmonic distortion.

Questyle M18i: Extended compatibility

During its development, the M18i was tested with numerous consumer phones and tablets to optimise compatibility. It is compatible with the iOS, HarmonyOS and Android operating systems for phones and tablets, and MacOS and Windows 10/11 for computers.
