| Material: CNC machined aluminum Color: Black / Silver Size: 51[L] X 16.5[W] X 8.1[D] (mm) | Operating System Required: Android phone and pad: Android 5.0 and above PC: Win10 1803 and above Apple cellphone: iOS (You need to buy an OTG cable for Lightning to Type-C.) Apple computer: Mac OS |
| DAC Capability of M12: PCM: 32kHz – 384kHz (16/24/32Bit) DSD: DSD64(1Bit 2.8MHz) , DSD128(1Bit 5.6MHz), DSD256(1Bit 11.2MHz) | Frequency Response: ±0.1dB(20Hz-20kHz) THD+N: 0.0003% DAC: ESS flagship USB DAC chip ES9281AC |
| 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. |

Mobile Headphone Amplifier with DAC
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.
Start Your Mobile Hi-Fi Journey
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.
Classic Black
Stylish Silver
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.
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.
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.
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.
Perfect Compatibility Plug and play, enjoy your Hi-Fi journey
M12 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.
