Good deal Sam. Glad to hear it. I figured the Sennheiser would work out for you. I didn't think the impedance mismatch between the input impedance of the 7700, and the output of the Sennheiser would be enough to be concerned about. Sounds like it wasn't. Yes we'll meet up on the bands sometime. You have my email address, so just send me a message when and where you will be, and we'll give it a try. I'm not at the radio at this time, otherwise we could do it now. Take care.
