M12 · Start Your Mobile Hi-Fi Journey

To greet mobile lossless music in the 5G era, Questyle released the M12 in 2021, a mobile Hi-Fi headphone amplifier with DAC, which integrates
Questyle’s core technology and carries on the gene of mobile Hi-Fi feature. M12 allows all mobile phone users to break through limitations of technology, cost and size of the audio circuit integrated into mobile phones, and feel free to enjoy lossless music from streaming anytime in any place.

Now, let M12 take you to your mobile Hi-Fi journey!

Sound by Questyle

The patented “Current Mode Amplification” technology is the fundamental difference between Questyle’s hardware and other terminals. The amplifier is to a headphone system what the engine is to a car. As the “engine” amplifier, it has a crucial impact on the improvement of sound quality. Benefiting from our self-developed SiP Current Mode Amplifier module, M12 is free from the power limit of operational amplifier chips and provides a totally different sound performance with the ultra-low distortion level of 0.0003%. It has ultra-high current output power and excellent sound control. It will fully dig out the potentiality of your headphones.

Smart Detection of Impedance Automatically self-adjust to fit your headphones
​When M12 is plugged into a headphone, the built-in smart detection system will start automatically to detect the headphone impedance and self-adjust to fit the headphone. Just like the auto shift of a car, M12 will self-adjust to high power level to drive high-impedance headphones with the Gain indicator showing red light, providing excellent dynamic performance. When driving low-impedance and high-sensitivity earphones, M12 will reduce the output level and accurately match their impedance, with the Gain indicator showing green light for low impedance.

Questyle and ESS team spent two years developing the mobile headphone amplifier with DAC and it will perform better than expected. The logo of both Questyle and ESS are put on M12 in order to mark the first cooperation between the two companies. ES9281AC, the ESS flagship USB DAC chip built in M12, has decoding capability up to PCM 384kHz/32bit and DSD256. Whether it is the deepest bass sound of the organ in European cathedrals or the strongest bass and guitar melodies in hard rock, M12 will always be able to capture the details buried deep in the soundtrack.

Support MQA Decoding

MQA (Master Quality Authenticated): Questyle M12 includes MQA Renderer technology, which can connect to an MQA Core signal and complete the final unfold of an MQA file. The M12 LED glows magenta to indicate that the unit is rendering an MQA stream or file. This delivers the final unfold of the MQA file.

Questyle M12

MQA is a new technology which removes digital distortion and packages audio streams efficiently into files that are small enough to stream. It can be integrated into your audio products in a very smart way and achieves the highest quality playback. MQA delivers the original sound, in the highest quality, using less data, and authenticates provenance.

My Best Sounding Dongle DAC

I spent a month doing research for a lite weight better sounding system for a on the go music rig. After settling on (and purchasing) the top four contenders it became obvious that the Questyle M12 was the winner. It adds to the listening experience without substantial battery usage and bulk.

Great Audio Equipment

It is very compact and is a very clean dac/amp for mid-range to entry high-end headphones. I used HD 650 S and it get very loud without distortion. Great buy!
