Questyle's second-generation mobile DAC, the M15i, embodies our finest tech achievements over the past decade. The M15i gives audiophiles lossless audio streaming anytime, anywhere -- and works flawlessly with traditional HiFi headphones, emsuring the best immersive audio experience.
The M15i is equipped with four Current Mode Amplification engines, and supports both 3.5mm unbalanced and 4.4mm balanced headphone connectors. It also features a manual gain adjustment for compatibility with a wide range of devices.
The "i" in M15i indicates certification by Apple's MFi program. MFi certification ensures perfect compatibility with iPhone/iPad and the Apple ecosystem. THe M15i meets Apple's strict requirements for external devices, especially in terms of power consumption, to avoid the risk of damage to phones and systems by connecting to arbitrary USB devices.
During development, Questyle Labs conducted extensive testing and optimization of M15i's compatibility with mainstream smartphones and tablets. The M15i provides high compatibility with iOS, HarmonyOS, and Android versions 5.1 and above. As for computer systems, it supports Windows 10 (version 18.3) and above w/o driver, and Mac OS. As such, all Hi-Fi headphone users can enjoy lossless audio on streaming platforms anytime, anywhere.
The M15i contains two groundbreaking, patented "current mode" amplification SiP modules developed by Questyle Technology. Its four Current Mode Amplification engines deliver clear, powerful sound. The low impedance characteristics of the current-mode circuit result in a bandwidth of up to 1MHz and distortion as low as 0.0003%, exposing the subtlest details hidden in recordings.
The risk of overheating and signal interruption during long listening sessions is extremely low thanks to Questyle's patented Current Mode Amplification and TOREX‘s efficient power management system, giving the M15i high performance and low power consumption
