Headset boost

I've attacked an old cordless phone and wired in a headset so that I can use
it hands free. I simply disconnected the phones mic and speaker and wored
them up to a headset socket.
While the mic works well; other party can hear me, I find that the earpiece
of the headset, even with the volume up loud is not quite enough if there is
any background noise.
So what I want to do is boost the phones speaker volume (maybe double)
slightly so that the
volume control on the headset has some range to it. I thought that a garden
variety transistor might do it, along with a resistor or two.
Problem is - I dont know how - I can only follow instructions when it comes
to this sort of thing - so I am hoping that someone here will provide some
help. Both the handset speaker and the headset speaker are in the vicinity
of 33-35 ohms

Thanks in advance.
