Can someone tell me if the headphones supplied with the N800 and
N810 are exactly the same please?

I have just bought a new N810 and thought it would be nice to leave the headphones supplied with it unopened to sell along with my N800 (when I get around to it ).

I know they look the same, but if the N810 ones are better in some way, I will open and use them (and the N800 will have to be sold with used headphones).

Thanks.
