Description

The QUESTYLE M15C DAC/AMP is a Cirrus Logic CS43198 flagship portable USB DAC/headphone amplifier that unlocks PCM 384kHz/32-bit + DSD256 hi-res lossless audio from codec-limited smartphones, tablets, laptops, and PCs. Its ultra-compact CNC anodized silver aluminum design (61.9x27.9x12mm) disappears into daily use while delivering patented 4x CMA SiP modules with 0.00028% THD+N, 1MHz bandwidth, and 42.79mW@300Ω balanced power—eliminating distortion, overheating, and battery drain even during extended hi-fi sessions. Plug-and-play across iOS, HarmonyOS, Android 5.1+, Mac, and Windows 10+ with no drivers needed, featuring 3.5mm/4.4mm dual outputs, manual gain control, and a smart LED sampling display for effortless optimization with sensitive IEMs, planars, and demanding headphones. The premium silver finish with TOREX power management and included USB-C cables protects the circuitry through travel and commutes, transforming any smart device into a serious hi-fi audio transport.

QUESTYLE M15C PORTABLE HI-FI ESSENTIAL

The Questyle M15C is a compact, high-performance portable USB DAC and headphone amplifier that boasts near-universal compatibility with mobile devices and computers, including iOS, HarmonyOS, Android 5.1+, macOS, and Windows 10 version 1803+. Equipped with Cirrus Logic's flagship CS43198 DAC chip, it handles PCM up to 384kHz/32-bit and DSD256 for true lossless audio enjoyment anywhere. Optimized power consumption prevents premature phone battery drainage, making it ideal for extended listening sessions.

AUDIO INNOVATION AND PATENTED CMA TECHNOLOGY

Questyle embraces simplicity to deliver high-fidelity audio to smartphone users, with the M15C overcoming smartphone audio circuit limitations through 4 independent Current Mode Amplification (CMA) SiP modules. This patented current-mode design achieves a 1MHz bandwidth and distortion as low as 0.00028% THD+N, revealing fine details from thunderous organs to electric guitars without overheating risks, thanks to TOREX precision power management.

VERSATILE 3.5MM & 4.4MM OUTPUTS WITH GAIN CONTROL

The M15C features both 3.5mm single-ended and 4.4mm fully balanced outputs, with manual gain adjustment to match headphone impedance and preferences for broader compatibility across IEMs and full-size cans. It provides ample power—up to 42.79mW at 300Ω on balance—for demanding loads while maintaining low noise.

SMART LED SAMPLING RATE DISPLAY

A data status LED lights up during playback: single red for PCM ≤48kHz, dual red for high-res PCM up to 384kHz or DSD256, offering instant visual feedback on audio quality. Leather protective cases and MagSafe covers are available separately for added portability and protection.

ELEGANT CNC ALUMINUM DESIGN & ACCESSORIES

Housed in CNC anodized silver aluminum (61.9 x 27.9 x 12mm), it includes USB-C cables for plug-and-play use without drivers. This driver-free design ensures effortless setup across platforms, elevating any device into a hi-fi transport for premium headphones. ​
