And yes it can be done
i have seen where members have constructed headphone amps in 9 volt battery cases so this should be easy
what I would like to see is a headphone amp in a pen
now THAT would be cool !
not something i would want or use but still high on the cool factor scale

The amp itself is probably not much of a problem. Finding a suitable power source is a different story....Maybe a cellphone/headset Li-Ion battery?

I managed to fit everything in a 9V battery case- the amp, input/output jacks, switch, and 6V power supply. It was not easy, though.... at all.
The power supply is the most limiting of all. If you just stick in those little watch batteries, yes, you can get a decent amount of voltage, but you won't have enough current to keep the amp powered for more than a few hours, and the volume won't be very loud anyway. Perhaps a few of the cell batteries in parallel or something... but it is not easy to do.

some of the new AD chips use a miniscule amount of power while outputting large amounts of current
i assume the output stage is Class B (cmos) and i can not testify as to how it sounds but there are options out there
just needs someone to take the hit

That's true... I forgot about that... I'll look into it.
