I have taken tyo using my Tungsten T to listen to seminar tapes using
Areoplayer and an SD card. Works great but the sound output is not
quite loud enough. Is there a fairly compact headphone I can buy
that includes a battrey driven amplifier, or pehaps a separate device
I can interface with that is not too bulky but will give me better
sound with my sports-style headphones.

Thanks.
