  • Review by B "Music Lover"

    I needed a headset that had a microphone to be able to communicate both on Skype and several video games that require that easier communication.

    Right away I was impressed by the ease at which my computer handled it and in less then 20 seconds it was fully operational. The quality of the sound was amazing and the easy access volume control is just icing on the cake. The microphone has great sound quality and there has never been a problem with anyone not being able to hear me or getting overwhelmed by background noise.

    Now, there is a few issues. Firstly the cheap plastic tabs that held right earpiece in place broke after a fall of only a foot. Second, the behind the ear design is uncomfortable with the way the headset secures itself. Add in a pair of glasses and the entire rig crosses over into painful until you become accustomed to it.

    Overall this is a headset with amazing sound quality both incoming and outgoing though wearing it takes quite a bit of getting used to.

    3 1/2 stars.

    I have always like the behind the head headsets better than the over the top kind. The other ones have typically lasted me about a year before the pads wear out or something just gives up and breaks. This headset fits well, sounds great, and the option of USB or .3mm makes it even better. I wanted to try out USB, but also wanted to be sure to be using my X-FI card (which is only used with the 3mm). Anyway, now I am strictly USB.

    Nice job on this headset Plantronics! From other experiences with Plantronics, I have found their customer service to be very good and they tend to stand behind their products. This means a lot to me.

    One thing I learned was that a USB headset when plugged in, will automatically switch the volume and mic to the headset from the speakers. In the past with 3mm I always had to have a switch and I know many have to unplug the other by climbing under the desk.

    This is a good, basic headset. It takes a little while to get used to the behind-the-neck headband, but it doesn’t muss your hair! The earpieces are NOT foam, so they won’t fall apart after a period of time. Getting a comfortable fit and getting the mic in the right place took some time. For the price, this is a great value since the audio to USB adapter will work with any mic/headset combination. You can configure it as a second audio card.
