Does having higher impedance correlate directly to better sound quality? - Page 2

post #16 of 18

You may get a bit more distortion in the lower end of the frequency response.

And you may get some interaction between the amp and the headphone if the headphone does not have a flat impedance response leading to some frequency response aberations: the amplifier will "appear" to have an altered frequency response.

No.

 

Although the higher ohm versions of the same models sound slightly better, it's not worth the trouble and expense.

Low Impedance high sensitivity are usually used for portable use, since they don't require much power, and are easy to drive. Low impedance headphones usually want more current, while high Impedance wants more voltage swing.

Neither one is "better sounding" as they both can sound great. If you had high Z (impedance) portable headphones, you would be up s**t's creek without a paddle lol. It's more of a preference of application and amplifier matching for choosing impedance. For example, planar magnetic drivers are low Z, low sensitivity, so they require a lot of current, but they also have a constant impedance vs frequency generally speaking, whereas dynamic headphones have varying impedance vs frequency. It's all pros and cons, neither is superior
