虽然我觉得这种便携的耳放应该没事，以防万一问一下。

耳放会把耳机烧掉么，如果会的话，看什么指标确认耳机可以兼容这个耳放？
我的主要耳机是b&w p7和其他普通入耳小耳机。

谢谢

入zx300,耳放就上台式,便携都是搞笑的

又不是台式设备。。。

没有兼容这种说法，只有是否合适

耳机阻抗，灵敏度。一般不是高阻抗或者低灵敏度的耳机用不着什么耳放。

pha1a更确切的说是便携解码耳放一体了，pha1才是纯便携耳放。

Non-Zero Output Impedance – Output impedance is one of the more common audible differences between anything with a headphone jack. As a simple rule of thumb, if the headphones are less than eight times the output impedance, the amp can alter the sound. So if you have the FiiO E9 amp, which has an output impedance of 10 ohms, you can only use headphones that are at least 80 ohms, otherwise the amp might change the sound. Breaking the “eight times rule” can result in muddy bass and even audible frequency response changes—especially with balanced armature in ear monitors such as Shures, Etymotics, Ultimate Ears, etc. See the Impedance article for more.

耳机阻抗应为耳放阻抗的8倍或者以上，否则耳放会改变声音
