im not sure with the motoralla(not saying that it's bad or anything) but what i did is bought warhawk that was bundled with a bluetooth headset. its a jabra, and it does get the job done. Warhawk is a decent game online too by the way so its a good option.

For your question about haze or army of two. i would say army just cuz the multiplayer option of you and your friend just literally having each other's back
