Summary: Needed headset with microphone for TELCONs with video and audio (called DCOs) and several units tried previously (Microsoft Lifechat and Logitech) were inconsistent and unreliable. A co-worker was using a Plantronics headset that worked and sounded good so after reading reviews, I picked up the Audio 478 USB Headset. I plugged the headset in and my PC recognized it immediately, loaded the drivers and it's working as expected. Definitely recommend !
Excerpt: I bought my Plantronics - .Audio 478 around a year ago, just today one of the wires came out and one of the speakers doesn't work anymore. However, from the experience I've had with this headset I'd say it's an amazing product for its value. The headset has pretty high quality audio so I was able to listen to music while playing my games. The microphone is amazing, too. I used it for a lot of YouTube videos and it works great, high quality too.
