We have upgraded our sound system with SHURE wireless mics now, and so I have (8) of these Countryman B3's up for sale that have Sennheiser connections. They are new and have not been used. I am asking $100 per mic. or $600 for all 8 of them.
Interesting that you say upgrade... but also why not keep them and reterminate for your Shure transmitters? Great price though, if they are new and unused that's a steal!
yeah I thought about keeping and putting new TA4F connectors on, I just don't have the time to do so. I've got my new equipment in already, so am selling off all of our old Sennheiser stuff and these unused B3's
