All the reports I've read recently have said that the 360 controller doesn't have any support for older Xbox headsets. Since my system didn't come with a 360 headset (which looks like a piece of crap anyway), I decided to give my Plantronics Halo 2 headset a shot. And lo and behold...it works! The sound is a but fuzzy, but it's clear enough to understand what's being said. I've yet to try it online (I've only sent voice messages w/ it), but this is is good news for anyone w/ a nice Xbox1 headset.
