Unverified搭配高灵敏度多单元动铁入耳（灵敏度≥110dB）应关注底噪而非推力，优选低输出阻抗（＜1Ω）且带增益档位可调的DAP，否则会有明显电流声和频响畸变94% similarUnverified多单元动铁耳机对输出阻抗敏感，放大器输出阻抗应＜1Ω（最好＜0.5Ω），否则会改变频响曲线导致声音失真，选购时查看Output Impedance参数93% similarUnverified灵敏度高的低阻入耳（如8Ω/110dB多单元动铁）优先看底噪而非功率：选输出阻抗＜1Ω且高增益档不啸叫的设备，否则电流声明显；这类耳机大功率台机反而容易过推失控91% similarUnverified只听IEM入耳耳塞（16-64Ω低阻）优先选低底噪机型，输出阻抗应＜1Ω，否则多单元动铁的频响会因阻尼失配而畸变，此时驱动力大小不重要90% similarUnverified低阻高灵敏度入耳（如舒尔SE846、8欧姆动铁）应关注低增益下的底噪控制，输出阻抗需<1欧姆以避免多单元动铁频响曲线畸变（阻尼系数原则：耳机阻抗应≥输出阻抗8倍）89% similar
