动圈旗舰阻抗差异大：低阻高敏（如32Ω/100dB）便携前端可推，高阻型号（300Ω如森海HD800S）需要电压摆幅大的耳放，用小尾巴会响度不足、低频松散

Unverified高阻抗大耳机（250Ω-600Ω，如拜亚DT880 250Ω、森海HD650 300Ω）需要输出电压摆幅足够的耳放，建议看规格中标注的高阻档功率，300Ω下应≥100mW才能推出足够动态和低频控制力82% similarUnverified耳机阻抗需与声卡推力匹配：300Ω高阻抗大耳需选高电压输出（≥2Vrms）的桌面声卡或强推力小尾巴，低阻高敏耳塞（<32Ω）反而怕底噪需选低输出阻抗（<1Ω）型号，否则易出现声音发闷或底噪明显81% similarUnverified推力匹配核心看阻抗：300Ω以上高阻大耳（如HD650/DT880 600Ω）需台式耳放单端输出≥300mW@300Ω或平衡口≥1W；便携小尾巴多数在32-300Ω耳机上够用，硬推300Ω以上高阻会明显动态不足81% similar
