FodsportsAccessories FX4 Pro Bluetooth Intercom (Speaker&Microphone)

Channel splitting dosent work. Microphone and speakers share a line so feeback errors occur

I purchased this at the same time I purchased my FX4. I have multiple helmets for different passengers, and this was part of the key in moving my FX4 from one helmet to the other. This is very different than the clip that comes with the headsets, and does not even remotely work.Edit: Upon further review, this does actually fit the FX4. This was the original mount that was used for this device, but they have since come out with a new one. Not sure the new one is on Amazon, but you can find it on the FodSports website. The new one allows you to easily move the unit off and on again, whereas this one, if you can actually get it on, has the release button blocked by the unit, so I had to stick the blade of a knife down in between in order to get my transmitter off. The newer model is great, and I've been moving the units between my kids helmets so when they ride with me they can talk to me without screaming.
