　　　我有一个很久都不明白的问题，在这里想请教一下大家：ＰＸ２００和ＥＳ５这两个耳机，阻抗是ＥＳ５高，灵敏度还是ＰＸ２００高，那为什么普遍都认为ＰＸ２００比ＥＳ５要难推很多呢？？

不明白了吧！这就是REAGO的参数没用论

..........等于没说!

参数确实不大有用的。。。。
KSC35好象是60欧的吧
但是它不是很难推~

这两个指标是测试得出的，但是与实际的使用（外壳形状，笛管等的设计）还是有关系的

啊!!!!!!!!!!我被骗啦!!!搞了半天还有这么多的因素啊!!~我原来以为只和参数有关呢!~唉~现在知道了,推不推得动首先要问过大家才知道!~嘎嘎,谢谢楼上的两位!~ [s:27]  [s:27]

就是你烧着烧着就得上二房了 [s:40]

你会发现好多低阻的家伙也很难推．

我只会考虑小不点最小那个的!~嘎嘎

考虑完了以后会考虑别的大一点的，然后研究电子管的，然后自己研究电路，然后是烧零件，然后就成骨灰．．．

光看参数不行滴 [s:40]

那你直接说烧钱好了

阻抗是32o和36o 差距不大
但是跟灵敏度还是有很大关系的 难不难推说到底就是灵敏度匹配阻抗
px200灵敏度是没有es5高的 而且相差的比较大

各家的指标在作横向对比时，其实可以考虑一定的误差在内。因为各个厂商测试时的标准都不会完全一样的。看两款耳机的指标，其实相差不大，所以考虑他们的特性差别时，从别的角度出发也许能得到更合理的解释
