Help on electronics please?

Question

is the higher the isolation of earphones the better??

also is the specs the same thing as isolation?

and what is impedance?

Answer 1

I don't think I can do a full explanation. You should study electronics to have a chance to understand this.

Isolation specification is how well the earphones block outside sounds, and higher is better.

There are many other specs beside isolation.

Impedance is a measure of the headphones resistance to current.
