Steelseries Siberia V2
Logitech headsets have great mics like the G930 for example
Sennheiser has some pretty decent gaming headsets with alright mics.
You could always go for the best Astro A40
(much cheaper than the A50 for the same hardware only wired)
Or you could just get a standalone mic like the yeti pro.
In the end it's all up to you, I will recommend steering clear of the Razer Tiamat 7.1 as their mic is inferior to most other mics in their competition.
