[TenTec] Headphones for ORION I?

[charles Lewis]

I find that the sound level from my old Pro-Luxe PX-921 (Radio Shack) headphones 
is sometimes not quite sufficient for me at the ORION's maximum volume setting, 
especially when I use a very narrow bandwidth setting for CW.  Can anyone 
recommend some good sounding, more sensitive headphones that are not extremely 
expensive?
