Tnx to all of you for your replies.
I won't post all the replies I received to the list (the large majority of
them came through the list anyway), but if anyone is interested I'll make a
compilation and send it via private email.
The majority of the replies seem pretty negative towards the Proset+ though.
I think I'll buy a HC4-element and try to find a way to make a boom to mount
it on my favorite headphones... This will be a lot cheaper and I'll be sure
the audio will be how I like it ! Moreover I never had any problems wearing
those headphones for 24 hrs yet...
PS Hope to log you all in Region 1 CW Fieldday next weekend, I'll be with
our club station ON6CK/P
