[Elecraft] Headphones

[n5ge at n5ge.com]

Ed,

I liked my Oticon aids so well that I talked my 87 year old mother into getting
some (she said she could hear quite well, thank you) ;o)  Mine are very much
like yours in appearance and features.

The aids she got were the newest since I got mine and they are smaller and
thinner than an almond, going behind the ear, but they have the speaker on a
wire that goes into the inner ear, and they actually have xcvrs in them so they
can communicate with each other saying things like that sound was from my side
so you don't need to increase it as much as I do.

The audiologist says that with these aids she can distinguish the direction of
sounds very well.  I hope to get a pair one of these days but as you know, they
are very expensive.  More than 2 KPA500s ;o)

73,
