[Supports high resolution sound] The M15i features the highly acclaimed ESS ES9281AC flagship DAC, which can handle up to PCM768kHz/32bit and DSD512. It’s almost inconceivable that something as small as the M15 can process and reproduce such demanding audio formats.
[Dual headphone outputs]The M15i, equipped with four current mode amplification engines, supports 3.5mm single-ended and 4.4mm fully balanced output modes. It also features manual gain adjustment, allowing users to choose the gain mode according to personal preferences, headphone characteristics, or the audio system, making it suitable for a wide range of apps and devices.
[Full Compatibility for True Lossless Enjoyment] During the development, Questyle Labs conducted extensive testing and targeted optimization of M15i’s compatibility with mainstream smartphones and tablets. Developers managed to achieve high compatibility with iOS, HarmonyOS, Android versions 5.1, etc. As for PC, it supports Windows 10 version 18.3 and above (driver-free) as well as Mac OS systems. Hence, all Hi-Fi headphone users can enjoy lossless audio on streaming platforms anytime, anywhere.
[Without Interruption]The M15i contains two groundbreaking “current mode” patent amplification SiP modules developed by Questyle Technology. Given that it operates in the current domain, the low impedance characteristics of the current-mode circuit result in a bandwidth of up to 1MHz and distortion as low as 0.0003%, capturing details hidden in the soundtracks.As a result, the risk of overheating or interruptions during long listening sessions is extremely low thanks to the patented current mode amplification, TOREX‘s efficient power management system, as well as the M15i’s high-performance and low-power consumption.
