Pros: Typical wireless headsets sound really terrible, like you're talking on a cell phone. With the DSP this headset sounds excellent! Note quite as clear as a Plantronics wired headset, but definitely not having to deal with a cord is well worth it

Cons: My buddy and I both have this headset. We use it with Skype, and occasionally we get an echo while talking, as though the mic is picking up the output from the earpiece. Probably happens every 5-10 minutes, not sure what is causing it.

Overall Review: After installing the Plantronics software, go into the Plantronics Control Panel, click on the "Devices" tab, and click the "Device Settings" button next to the drop down menu. Make sure the "Audio Bandwidth" is set to "Wideband" rather than "Narrowband." This improved the sound quality threefold.
