3 out of 5 eggsNot Worth the Money

Pros: Sound quality is good and the microphone is very clear. Requires almost zero configuration for Microsoft Lync.

Cons: Padding around the top of the headset is very uncomfortable. When I wear them for more than 30 minutes it makes the top of my head very sore. Also since the top is not wider they tend to slip off my head.

Other Thoughts: We use these at work. I'm a network engineer that is sometimes on calls for 2 and 3 hours troubleshooting problems. I tried to use these for a month before going out to buy a USB adapter for my old Razer Carcharias headset (our laptops do not have the typical audio jacks). I personally would not buy the money for these. There are plenty of gaming headsets that are much for comfortable and provide the same audio quality. Sure, they may not look as professional but looks to me do not outweigh comfort with headsets.
