Welcome to the world of truly mobile HiFi

In this complex world, we pursue simplicity. Don’t be fooled by its small size. The M15 offers uncompromising performance and best-in-class fidelity, giving you the ultimate portable audio experience.

Inspiration

The era of 5G has brought music streaming from smart devices fully into the mainstream. As more and more music platforms launch lossless audio streaming services, mobile hi-res audio has changed from a neat gimmick into a real and growingly popular way to enjoy high-fidelity music. However, it’s often impractical to use traditional HiFi audio equipment with your smartphone on-the-go, due to size and power consumption. To solve this problem, the M15 was born: it distills all of Questyle’s expertise and technologies into an amazingly powerful yet compact mobile DAC & amp.

Two Independent SiP

Greater Dynamics, Richer Details

The M15 contains two of Questyle’s patented CMA (Current Mode Amplification) SiP modules, for a total of four CMA amp engines. This quadruple drive amplification circuitry gives an outstandingly strong output that can drive almost any headphone. Questyle’s Current Mode Amplifiers are characterized by their small footprint, low voltage operation, and minimal power consumption. Current amplification has a naturally low impedance, affording the M15 a bandwidth up to1MHz, distortion as low as 0.0003%, and the ability to reproduce every detail hidden deep within any track.

3.5mm TRS / 4.4mm TRRS outputs

Manual Gain Adjustment

With its four CMA amp circuits, the M15 supports both unbalanced (3.5mm TRS) and balanced (4.4mm TRRS) outputs. It also has manual gain adjustment via the slider on the side, which makes it easy to choose high/low gain depending on the connected headphone, speaker, or HiFi system.

Impossibly Low Noise Floor, Complete Sonic Immersion

Purest Sound, Anytime, Anywhere

Only a black background can reflect rich color. With its incredibly low noise floor, the M15 allows all the details of your music faithfully ring true.

Top-of-the-Line Decoding

World-Class Digital Analog

The M15 features the highly acclaimed ESS ES9281AC flagshipDAC, which can handle up to PCM384kHz/32bit and DSD256. It’s almost inconceivable that something as small as the M15 can process and reproduce such demanding audio formats.

High-Efficiency Power Management

The M15 features TOREX High-Efficiency Power Management, which could bring out low power consumption, no overheating , longer battery life, longer playback.

The M15 Connects you to the Streaming Era 

The Easiest Way to Enjoy any Hi-Res Lossless Library

The M15 supports almost all music streaming platforms worldwide, including Apple Music, Tidal, QQ Music, among others. It fully supports and decodes ALAC, FLAC, MQA, andother lossless formats.

Unparalleled ease of use, Plug-and-Play

M15 is fully compatible with Android 5.1 and above systems on popular smart phones and tablets. For PC, it supports Mac OS and Windows 10 version 18.3 and above with no additional driver installation required.
