Its work excelent and easy to set up especially on connecting via wifi thru my phone connect to the projector can also connect to laptop as you can see on the video because it comes with the hdmi cord. when on low battery and trying to charge, headset just switches off. Also background noise is almost clearer than the person talking. However, by the time we put it up on the wall we are satisfied with how it looks. locking mechanism is easy to release and lock. To many scratches. Dre fans might not appreciate her ?version? of him. I have bought these more than once now and simply love them! (About Half full) Very glad about my decision.
