I'd echo the same warning others have posted - I own a pair of A40's (2013 edition + mixamp, although the mixamp is now an expensive paperweight) and A50's (first gen), good sound, terrible support from "Astro" (Skullcandy). The one thing you should be able to rely on when over-paying for a "premium" product is half-decent after-market support.
There's still life in both my headsets but I'll never buy Astro again (A40's, developed vibration/rattle in left ear within 6 months of purchase, Astro wanted £100 to "service" them - fixed myself, currently developing the "loose microphone" issue that plagues their headsets - A50's, mic/driver fiasco, wireless connectivity issues, constant problems - awesome when they work but may as well flip a coin each time you pick them up).
Also should be noted, Astro Gaming is now just a brand name owned by Skullcandy (bought from Astro Studios in 2011) - Astro's good reputation entirely belongs to Astro Studios, Skullcandy are milking it dry.
