Purchased this headset for my mother who is in a Assisted Living Facility to assist my mother with speaking. Her voice is very soft and can be difficult to hear at times. After only 1-day of use the headset starting shocking. Yes, SHOCKING!! Her caretaker walked in to hear her screaming it’s shocking me!!! It worked Perfectly until it didn’t…. This could have been catastrophic for her. I don’t recommend
