Moreover, do high impedance headphones sound better?

The high-impedance versions sound more transparent and clearer, bass definition is better, and the soundstage is more spacious. The lower moving mass of the 250- and 600-ohm headphones' voice coils is lighter than the 32-ohm models, and the lower mass is part of the reason high-impedance headphones sound better.

Beside above, is higher or lower ohms better headphones? The higher the ratio, the better, so a higher impedance headphone is better for this point. Basically, it's about how much control the amp has over the headphone diaphragm. Lower impedance means louder at the same voltage. This does mean that a high impedance headphone might not get loud enough from some devices.

Just so, which impedance is better for headphones?

Headphones with higher impedance (25 ohms and over, approximately) demand more power to deliver high audio levels. As a result, they are protected from damage caused by overloading. They can also be used with a wider range of audio equipment.

Is impedance good or bad?

It is neither good or bad, it just changes the requirements for driving a headphone. A low impedance headphone can will require more current. Efficiency is also different than impedance, btw.
