That's the package I got for the CRJ. Works great. Went through 2 Plantronics setups and got rid of them. The gain on the 5X5 is what makes it better. They also sell a filter that fits inline of the earmolds. Get that too. Or the acft sounds get pretty loud in some of the CRJs. Nothing like talking normally and then "SELCAL, SELCAL" chimes in about 20 times louder.
