I tried the stock headphones/mic for the first time on the bus/metro the other day and i couldn't hear more than what you would hear from someone listening to headphones next to you!

I thought the device couldn't give them enougth power or something, so once at home, i tried with big headphones (sennheiser HD555) and i had loud and clear sounding headphones.

So now i need to find a headphone with mic that i can actually use on the road!
