I've owned Turtle Beach headsets for over a decade. This set is EASILY their best thus far! The 600 had great sound, this set is even better. It has two usb transmitters (dedicated xbox and pc) and there's a button the the set to swap between them. It's very seamless and works really well. The 600 series would lose connection as I walked around, this set does not. Conversations are very clear, both Bluetooth and in game. The major problem with TurtleBeach has always been longevity. The joints at the earcuffs have always broken away on me. This set is completely redesigned and very comfortable. I'll update in a year. So far, they're absolutely worth every cent!
