Why is the P21 better than using a BlueTooth ear piece or USB headset for chatting on PSN?
If you’re using a BlueTooth™ ear piece or USB headset to chat on PSN, then you’ll need speakers to hear the game sound. The drawbacks to this are; (1.) the game sound from the speakers will disturb others around you who aren’t playing the game, (2.) one of your ears is covered by the ear piece, so you can only listen to the game with the other ear, (3.) the game sound can be picked up by your mic, which can be annoying to other players on PSN, especially when it causes feedback, and (4.) you have to stop what you’re doing to control the game and chat volumes because they’re not easily accessible. The P21 solves these problems by integrating the PSN chat with the game sound in a stereo headset with a convenient amplifier that clips on to your belt for easy access to all of the controls.
