This configuration delivers authoritative low-end response, clear vocal reproduction, and faithful high-resolution audio playback. A dedicated high-definition ADC chip enables 24-bit/96kHz recording, making the JM7MAX suitable for music, calls, live streaming, and microphone input.                                                                                Ultra-Low Noise and High Signal Purity                With a signal-to-noise ratio of ~115dB (32Ω, A-weighted) and an ultra-low noise floor of ~2.5µV, the JM7MAX achieves a pitch-black background that reveals micro-details without audible hiss. Total harmonic distortion plus noise is measured at ~0.0025% @ 32Ω, preserving the integrity and transparency of the original signal. Channel crosstalk reaches ~-76dB @ 32Ω, ensuring precise stereo separation.                                                                                Powerful Output and Broad Compatibility                The JM7MAX delivers ~118mW of output power @ 32Ω (THD+N &lt;1%) with an output impedance of ~0.5Ω, allowing it to drive both low-impedance high-sensitivity earphones and higher-impedance monitors with ease. It supports plug-and-play operation with Android and iOS devices via Type-C, as well as macOS and Windows 10 or later computers that support the UAC 2.0 protocol. (Note: Not compatible with UAC 1.0 devices such as Nintendo Switch, PS5, or Windows 7 PCs.)                                                                                Premium Build and Silver-Copper Hybrid Cable                The housing is precision-machined from aluminum alloy using 5-axis CNC engraving, finished with a fine-blasted and anodized matte silver surface for durability and a premium feel.
