I bought this primarily for use as a cordless headset for gaming. Setup was tricky: it took two different attempts using different configuration methods to get any sound out of the unit. Once it was connected and configured, I found that it was utterly useless for gaming. There is no way to use both the headset and the PC speakers in the same game. This means that I have the choice of either using my PC's internal card for DoD:S or using the 510. I cannot, for example, use the 510 as a mic and use my speakers for stereo sound. This makes it useless for gaming, since I cannot tell the location of other players and in-game entities by sound. To top it off, the audio quality was abysmal. While I stand by the multiple Plantronics wired headsets I've owned, I was shocked by the  low audio quality of this headset. Both the in-game sound test and a recording program played back my voice with fidelity below that of an old rotary telephone. I am returning this device tomorrow and giving up on Bluetooth entirely after this disappointment.
