Headset connection with players on buddy list

Is anyone else having trouble connecting with each other on the headsets and no buddy name highlight color?
It seems like lately this has been happening to more players than just me and yesterday I was on the deathstar and there where a few of us not connecting so i switched teams and it fixed it vash could hear me. My headset works great I already know not to go over 50 buddys on my list so why? Is it the server location relative to the player,a gamespy problem,server ping? its like the lottery who will connect with who lol.

haha i kno mine feels like that sumtime lol and it not just grizz there r others i have trouble hearing sumtimes 2 x.x

I can't hear anything but static and random jibberish out of mine nowadays.
