I've had the non-SE model for about a month now and in the 3 days I've had a lot of issues of the sound randomly cutting in and out like it loses connection to the dongle. I put the dongle on a USB extender about 2 weeks ago so the dongle is about 2 feet away from the headset when the issue is occurring.
I've also had sound cracking issues in a few games, the one I hear it the most on is World of Warcraft when I am on dragon mounts with their wings flapping.
Since only the mic is different in the SE model (as far as I am aware) I figured this would be the best place to post my issues so far with the Virtuoso headset.
