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.
