Product Overview: Sound, Aesthetics, and MFi Certification
The Questyle M12i Hi-Res Lossless Portable DAC & Amp offers an exceptional audio experience by seamlessly blending superior sound quality, striking aesthetics, and Apple MFi certification. As an update to one of the best value DACs globally, it features automatic impedance detection, supports up to PCM384kHz/32bit and DSD512, and optimizes power consumption to prevent excessive battery drain on mobile devices. With a USB-C input and 3.5mm headphone output, the M12i is designed for versatile connectivity.
Introducing the 2nd Generation Mobile Headphone Amplifier
At the 2024 CES exhibition, Questyle introduced the 2nd Generation M12i, building on the success of its predecessor. This model continues to deliver high-performance audio signal processing, surpassing the limitations of integrated phone audio circuits. Equipped with Questyle's unique Current Mode Amplification and the ESS flagship USB DAC chip, the M12i ensures a superior audio experience for HiFi headphone users, allowing them to enjoy lossless audio content from streaming platforms.
Hardcore Technological Aesthetics
The Questyle M12i features a Kunlun glass window design that showcases the intricate craftsmanship of its internal circuitry. This design not only highlights the essential components for signal processing but also exemplifies technological aesthetics, making the M12i a visually appealing device.
Apple MFi Certified for Performance and Compatibility
The "i" in M12i signifies its Apple MFi certification, ensuring perfect compatibility with iPhone and iPad devices. This certification guarantees that the M12i meets Apple's rigorous standards for power consumption and device compatibility, preventing potential damage to phones and systems from incompatible pairings.
Patented Low Power Consumption SiP Current Mode Amplifier
Questyle's patented "Current Mode" amplifier technology is a standout feature, offering ultra-low distortion of 0.0003% and high current output capability. The M12i's CMA module, combined with TOREX's efficient power management system, delivers high performance with low power consumption, reducing risks of overheating and interruptions during extended use.
Full Compatibility for True Lossless Enjoyment
The M12i is extensively tested for compatibility with mainstream smartphones, tablets, and PCs. It supports iOS, HarmonyOS, Android 5.1 and above, Windows 10 and above, and macOS, ensuring that HiFi headphone users can enjoy lossless audio content from various streaming platforms anytime and anywhere.
Smart Impedance Matching
The built-in smart impedance detection system in the M12i automatically identifies the impedance of connected headphones and adjusts accordingly. This feature operates like an automatic transmission in a car, optimizing the gain based on the detected impedance. Whether connected to headphones or used as a mobile DAC with HiFi systems or active speakers, the M12i provides the necessary output for an optimal audio experience.

Loving it
This is my first ever IEM that I purchased after research of couple of months. And I can say that this was a good decision on my end. Cable is good. Buds look stylish. Comes with a small carry pouch and 6 pairs of ear tips. Sound quality is awesome. Love the instrument separation. Customisable EQ gives them versatility. You can actually experience how other IEM sound just be playing around with the EQ.

a must have for any audiophile.
They sound just amazing, I would say that the app a little rough to use. I can vouch they sound amazing. better than most of the tws which are out there in the market. Also, the Online dsp, gives a little edge it you want to tune them, and you can also upload your on DSP. Overall at this price point, It' a 10 on 10 deal.

very much satisfied
Audiocular’s MemoryFlex tips combine the plush comfort of foam with a surprisingly clean and controlled sonic presentation. Unlike conventional foam tips that can blur detail, these retain clarity while still absorbing harsh peaks. At ₹249 for 3 pairs with case, they’re not just sonically impressive, but also one of the best value upgrades you can buy
