Happy holidays. I just got a new G933 gifted to me for Christmas by somebody that didn't know that I already have a first gen Astro A50. Would the G933 be an upgrade over a first gen Astro A50 or should I stick with the Astro? I'm happy with my A50s, but they are over 6 years old at this point, so if a newer (although cheaper) set of wireless headphones has a new feature or two I'd like to take advantage of them. Otherwise I can just stick with my gen 1 A50s and exchange the G933s.
