I purchased these while I was on a 2 month work trip last year. They worked very well but I don't need them anymore. They have clear audio, a decent mic (for a gaming headset), are easy to use and setup, and have a decent battery life.

Here is the link to the SteelSeries listing on their website: SteelSeries Arctis 7 Wireless

The Arctis 7 Wireless retails NEW for $169.99, but I am selling my USED one for $60.00.
