radio+sport+headset

Tony --

I have one of the RadioSport headsets and have used it exclusively since shortly after receiving my 6700.  Call the guy at RadioSport and talk with him --- he has a special package mic designed for the Flex line -- In fact, he supplies Flex Radio with such headsets for their personal use.  You will not find a better headset for comfort or performance.  I got mine with an interchangeable mic element suggested by RadioSport.  Call the owner of RadioSport and talk with him -- he knows the Flex radios and what works, etc. -- Good luck,  73,  HNY,  ****, K9APW, Madison, WI 

Dave at Radio Sport will supply you with what you need in 95% of cases, and what he can't supply, he'll give you the info to make it yourself.

You said unbalance for the rear and unbalanced for the front.  You obviously meant balanced for the rear (XLR) since you have a 6500 and you mention in in your follow up.  One thing to note about the CS6/XLR cable; Everything about his cables are top quality, EXCEPT the XLR connector used.  It is a bad Chinese knock-off of a Neutrik and is easily broken.  I broke one without much effort at all.  I replaced it with a good XX series Neutrik XLR.  It will never break again short of being run over by a Hum-V.

FYI:  Dave at RadioSport will supply you with the pin-out information your need if you want something he doesn't supply or can't get quickly, which is your case.  I've bought a total of 5 of these headsets; 1 for me and 4 for my club.  I got them with various cables and elements for different radios and had to make an adapter for one situation.  I even got Dave's PTT pedal interface as well.  He has a lot of options and bends over backward to help out.  Great product and great support.

Do keep in mind that you CANNOT use an electret mic into the back of the 6000 series, as there is no bias voltage available on the rear connectors.  The electret can only be used on the front connector.  You'll need a HIGH OUTPUT dynamic for the rear connector, which Dave can recommend and I suggest contacting him directly for the latest info on that.  The electret mic has the widest dynamic/audio range, but if you want to use it into the rear, you'll need some sort of phantom supply unit in between the headset and rig.  Yes, even the Flex 6000 series has some limitations, albeit few.
