Questyle M12i is a compact USB DAC headphone amplifier built for listeners who want studio-grade sound without carrying extra gear. Powered by the acclaimed ESS ES9281AC flagship DAC chip, it supports resolutions up to PCM 768kHz/32bit and DSD512, giving your phone, laptop, or PC the audio power that built-in circuits simply can't deliver.

What sets the M12i apart is its MFi certification, meaning it's officially approved for safe, seamless use with iPhone and iPad. Whether you're commuting, working from a laptop, or gaming on a PC, this portable USB DAC amp plugs in and upgrades your sound instantly, no extra apps or drivers required for most devices.

With a noise floor below -130dB and a frequency response stretching past 80kHz, the M12i is engineered for listeners who can hear the difference between "good enough" and true high-fidelity audio.

Key Features

• ESS ES9281AC Flagship DAC Chip — Decodes audio up to PCM 768kHz/32bit and DSD512, so you hear far more detail and depth than a phone's built-in audio chip can reproduce.

• MFi Certified for iPhone/iPad — Officially certified by Apple, so it integrates safely with iOS devices without power or compatibility issues that can come from uncertified USB accessories.

• Broad Device Compatibility — Works across Android, iOS, Windows, and Mac, so the same amp travels with you from your phone to your laptop to your tablet.

• Ultra-Low Noise Floor (Below -130dB) — Patented Current Mode amplifier technology keeps background hiss out of the mix, even with sensitive in-ear monitors.

• Wide Frequency Response Over 80kHz — Delivers a true Hi-Res listening experience with high signal-to-noise ratio and low distortion for clean, accurate sound.

• Compact, Portable Design — Small enough to slip into a pocket or laptop bag, making it easy to bring high-fidelity sound anywhere.

Why Choose the Questyle M12i USB DAC Headphone Amplifier

Most phones and laptops compromise on audio quality to save space and cost. The M12i solves that by moving DAC and amplification duties to a dedicated external device, so you get dramatically cleaner, more powerful sound from the same headphones you already own.

It's a practical upgrade for anyone who streams lossless music, edits audio, or simply wants clearer calls and richer sound during everyday use. The MFi certification also means iPhone users can plug in with confidence, without worrying about device damage from unauthorized accessories.
