You can not look up any this! I dont really need a mic as the only co-op gaming I do is for League of Legends so I knew I didnt want to pay more than $25 - $50 for a headset with a mic feature. First off, full marks for service and delivery of this product, its arrival on Christmas Eve exceeded my expectations! These fit the best. I like the idea of using a screw to secure the rack to the hatch receiver instead of just a pin, which makes it really stable and no wobbles at all. These Ariats are very comfortable. Keine Blase, keine Druckstellen. If you are a "B" width, these will be too large. Constructing it was a bit difficult. That little bit of extra length and the adjustable strap lets me get these babies to stay on with absolutely no pinching or slipping off my feet.
