Audio Parameters
耳机输出性能与参数（6.35mm输出，线路输入）
Output power L+R≥30mW+30mW (16Ω, THD+N＜1%, 0.7Vrms) Crosstalk ≥76dB (1kHz@32Ω)
L+R≥60mW+60mW (32Ω, THD+N＜1%, 1.4Vrms) Noise floor ＜25uV（A计权）
L+R≥185mW+185mW (300Ω, THD+N＜1%, 7.4Vrms) SNR ≥95dB (A-weighted)
*传统振膜通常依赖特定粘合剂将音圈粘合在振膜表面，这不仅增加振膜整体重量，还可能导致动圈运动时的动态失衡。局部重量分布不均会引起振动异常、改变振膜顺性，甚至因音圈擦圈而产生失真，最终影响单元整体表现。 ＜0.06% (1kHz/-16.3dB@32Ω) Dynamic range ≥95dB (A-weighted)
Frequency response 20Hz~65kHz: attenuation＜2.9dB Peak output voltage 46.2Vp-p
