Plantronics Audio 550 DSP HeadsetMakaveli -
To install your headset, just plug it into a free USB port. The only down side to installing it is that the headset disables your speakers immediately. Now, go to the download page on Plantronics' website and download the PerSono software and install it.
The software which you use for the headset is called PerSono. It is a small program that goes hand-in-hand with the Windows audio controls. There are two different tabs – headphone and microphone. Under the headphone tab, you can change the balance, bass, and treble of your headphones, as well as which style you’d like to have on. The different styles you can choose from are shown on the right-hand screenshot. The speaker test is a sound file that starts by making a whooshing noise in the left ear and it gradually gets louder and moves to the right ear. At the end of the test, it makes a crashing noise with bass in both ears.
Under the microphone tab, users can change the microphone’s volume as well as test it. When you test the microphone, it tells you to start talking and then plays it back.
The display in the middle of the program shows your selections below with blue bars. You cannot make changes within the display; you must do your modifying in the section below with the sliders.
