Hi.I need to know what's the different between the Panasonic RP-HC250 and RP-HC300 Headphones ?

Question

I need to know the different because everybody says that it is the same.
And I don't believe it.

Answer 1

Both headphones have the same size magnets, the same frequency response range and operate on the same battery.

It seems the only difference is the model number.

The model number may have changed from one year to the next, so the 250 may be an older model, but probably performs the same as the 300
