5W= U. So be forewarned. The noise cancelling is great, too. - Pro camera apps. Great headset to replace my broken corded gamecom 788s. No software in Windows 10. They protect my AirPods soooooo well! I bought a wallet that is attached to my phone so now when I lose my wallet or phone I just use my wifes phone and call my wallet. the upper flap/lid does not seperate from the case when opening. Automatic pause when taking one (or both) of the buds out of the ear is a very useful feature.
