Quest has no limits. QPM, the flagship portable lossless player of Questyle, beyond itself once again.The more complicated the world is, the more concise we are. We hope you can enjoy high-quality music in an easy way anytime and anywhere.


Inheriting Questyle’s distinctive design style, QPM is visually impressive for its tucked twist, curved surfaces and smooth lines, as well as a more comfortable grip.

Different from the last two generations of Questyle players, 3D glass is first time used for the front and the rear panel of QPM. By overcoming various challenges of processing, different materials are combined together perfectly, which makes QPM a work of art.

Your Portable Music Hall

The Portable Lossless Audio Player, QPM, can be used independently and loaded with tens of thousands of lossless music files, which will become a music hall in your pocket.

Portable DAC & Headphone Amplifier

In addition, QPM can be used as a DAC for mobile phones via USB connector and it will provide you with significantly improved sound.


Questyle’s patented Current Mode Amplification technology is set apart from other technologies adopted in traditional amplifiers. It will provide users with an experience of being there and listening to the original sound.
QPM uses CA630 and CC630, the pure Class A Current Mode Amplification modules featuring fully discrete structure and SIP (System In Package). Benefit from the SIP process, the output power of QPM increases by nearly a half compared with QP2R, and the quietness increases by two and a half times.


QPM with the High BIAS setting indicated by red light of the BIAS indicator on the side of QPM, the amplifier works in pure Class A state and provides endless energy for the amplifier. Plus the 4.4mm full-balanced output, QPM will give full performance to your headphones and bring you an exceptional listening experience.

Pure Class A BIAS Control

QPM supports pure Class A BIAS Control system. With the High BIAS setting, the output static current doubles, the THD+N and higher harmonic distortion drop to the lowest level, which is like driving a super sport car, just imagine the car is set to “RACE” mode.QPM immediately attains stronger power and quicker responses, enhancing the performance dramatically.
