In this complex world, we pursue simplicity.

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.

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.
Welcome to the world of truly mobile HiFi.

Questyle M15

  • Two independent CMA SiP modules
  • Four total amplification circuits
  • 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 Mode amplification has a naturally low impedance, affording the M15 a bandwidth up to 1MHz, distortion as low as 0.0003%, and the ability to reproduce every detail hidden deep within any track.

Compatible with even more headphones

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.

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. In testing, the M15 was able to achieve a noise floor of -130dB.

When playing audio, the data status indicator will illuminate one of the following colors:

  • Green: indicates the audio sample rate is 48kHz or less.
  • Red: indicates hi-res lossless playback.(Hi-res lossless refers to PCM 88.2kHz~384 kHz, or DSD64~DSD256.)
  • Magenta: indicates the M15 is performing the final unfold of an MQA Core stream.

ESS Technology

World-class digital to analog conversion ESS ES9281AC DAC offers top-of-the-line decoding. The M15 features the highly acclaimed ESS ES9281AC flagship DAC, 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.

  • DAC Capability
  • Low power consumption, no overheating
  • Long battery life, longer playback
  • Unparalleled ease of use
  • Plug-and-play, no drivers needed
  • Your HiFi, anytime, anywhere
  • Metal housing, transparent cover
  • Minimalist on the outside, stunning on the inside

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, and other lossless formats.
