I agree with the SteelSeries, great headset! Though if you don't mind going wired you could pick any studio grade headset and pair with a separate mic (or if you want it attached modmics are good).
That way you don't have to compromise on the quality of the headset while still being able to use voice online.
I'm currently set up all wired, and use my bluetooth earbuds for if i want to go away from my desk (like if i want to listen to videos for which when laying down a headset would get in the way)
The black metal part reminds me of my futon couch, has a similar mechanism for when you fold/unfold it. Could this be an arm for some kind of recliner chair?
