Unverified监听耳机线优先选OFC无氧铜或单晶铜（OCC）导体，OCC晶界少、传输失真低，适合追求还原的监听场景；镀银线会略微提亮高频，改变原始音色，不利于监听的真实性判断77% similarUnverified单晶铜(OCC/UP-OCC)导体因晶界少、传输损耗低，比普通无氧铜(OFC)在低频量感和中频密度上更饱满，适合追求温暖厚声底的耳塞（如动铁多单元）74% similarUnverified桌面屏风本质是吸音而非隔音，聚酯纤维密度需≥25kg/m³ 才有实际吸音效果，NRC降噪系数≥0.4的产品才对中高频人声有明显改善，密度过低的产品仅有视觉遮挡作用69% similarUnverified丝膜球顶高音听感柔和耐听适合长时间人声，金属（铝/铍）球顶高音解析力强延伸好但对录音差的音源和劣质功放更挑剔69% similarUnverified带娃出行选购需确认最大音量≥85dB，白噪音需盖过环境噪音才能起效；纯电子合成音机型通常音量上限更高更稳定，采样音机型高音量下易失真68% similar
