Apparently works with the Xbox One S as well as the original. Was looking for a couple of spares for mates etc and figure even if they are slightly lower build quality it's better than $75ish for a genuine one
Limitations (that I can ascertain besides potential build quality issues) are:
* Xbox One ONLY (no pc compatibility) even though the landing page suggests it, the FAQ says it doesn't.
* No 3.5mm socket
im pretty sure with these you have to plug a receiver dongle into the xbox one…i.e. theyre really a ghetto solution which doesnt use the xbox's inbuilt wireless
