Questyle Audio is a brand we all know for its class-leading premium products in the audio industry. For the past many years, the brand is dedicated to creating high-fidelity audio products on both portable and desktop levels. Today, Questyle has released its mobile high-tech DAC/AMP device, Questyle M12.
Questyle puts together the latest technology and years of experience of professional engineers to bring us a HiFi mobile device that is capable of decoding high-resolution audio signals with an ultra-low distortion rating of just 0.0003%. It has intelligent resistance detection technology that adapts to different headphones with different impedance ratings. The M12 supports MQA decoding and rendering along with Hi-Res PCM and DSD decoding ensuring the best Hi-Resolution experience for its users. Questyle M12 is available for 139.99$.
Questyle M12 features the brand’s self-patented “Current Mode” amplifier technology. As the “engine” of the headphone system, an amplifier plays a vital role in the output quality. M12 is not limited by the power of OPAMP chips, it has ultra-high current output capability and control. Even with such a powerful driving force, the device has an ultra-low distortion rating of just 0.0003%.
Questyle has partnered with ESS Sabre Technologies to bring a true-to-life high-resolution audio performance with its M12 Mobile DAC/AMP. M12 is equipped with an ES9281AC decoding chip that enables it to support high-resolution audio signal decoding with ultra-low distortion and clean noise-free background. It supports PCM decoding up to 32-Bit/384kHz and DSD up to DSD256 natively.
Questyle Labs has done a lot of testing and targeted optimization on the compatibility of the M12 with mainstream mobile phones and tablets. It is fully compatible with any smartphone running on Android V5.1 and above. For PC is supports Windows 10 and MAC systems with no requirement for any specialized driver installation.
Questyle M12 is quite compact and versatile to use. Users can carry it around in their pocket along with their smartphone with no trouble at all thanks to its small compact size.

DSD: DSD64(1Bit 2.8MHz) , DSD128(1Bit 5.6MHz), DSD256(1Bit 11.2MHz)
– Output Power:
Built-in smart detection circuit will automatically self-adjust the output power to fit different
impedance of headphones.
RL=16Ω，Po=46.11mW;
RL=32Ω，Po=26.71mW;
RL=300Ω，Po=12.26mW;
When the detected impedance is less than 70Ω, M12 will self-adjust to low gain output.
When it is more than 70Ω, M12 will self-adjust to high gain output.
When it is more than 600Ω, M12 will automatically switch to 2Vrms line out.
