Well I did contact EA support, and I got this response
My question-I think I got messed up headset adapters because if I wigle it around I can hear other people’s voices but very quietly. Also I can’t talk out bound. Tried both adapters on both the drum set a guitar and no go. Is it possible to get some replacements?
EA-Unfortunately at this time the adapters are not individually replaced, and the only option would be to see if your local video game retailer may have them in stock. But for now there is no replacement adapter that we can provide at this time.
In other word #### you. So the only option for now is to get a wireless headset.
