Do they get better sound than the Sony wireless Bluetooth headset?
Um,,,, Mine is a Sony, but in the event you were addressing someone else, YES, any full headset gets better sound.
Don't get me wrong, I would love to have 7.1 surround in my ears, so I can hear a cricket squeak as someone tries to sneak up behind me, but I just can;t spend that much cabbage on it.
I hear the Turtle Beach Headsets are phenomenal, but then again they cost up to $350.
SO it is all in the value. If you think you would use it, then it is worth it. If you are a casual online player like me, it does not justify the cost. I have surround sound in the living room and use the ear piece for communication, such as it is.
Check out these Threads for a stunning example of how you should utilize the headset tools.
Although it is not perfect every time, these guys are at least playing with strategy and cooperation.
