I have been looking into buying a pair of Astro A50 I have heard there is a newer version of it that has recently came out and I have heard that many people don't like the mic on the older version I was hoping if anyone can tell me if the mic is much better than the previous generation and any other problems I may encounter because I don't want to pay $350 for something I won't like. also i'm wondering how are they with glasses and is it extremely snug? (I have a larger head).
