[TenTec] need headphone advice

[KZ2G]

i'm going to be doing some cw mountain topping from the 11th floor of the
Hofstra University Library.  You can see miles in every direction at 300+
feet.  I'm going to be using my Yaesu FT-100D with 7 watts and a Miracle
Whip antenna.  But can't use the rig's speaker in a library.  Any
suggestions for a cheap, lightweight mono headphone set that will work AOK
on the FT-100D?
