Samson SW7A7SQE Reviews

I finally got to use this mic at an event and the headset died twice. Even when I placed a new battery in it. I will be returning it. Then my friend who as DJing there said he had issues with the headset as well, with feedback sensitivity and the battery. Dont buy. find something better. I had to yell for half my event. Terrible and embarrassing.

I like this mic, I have used the Airline 77 AH1 model as well and I like the AH1 model a little better than this one which is the AH7. The AH1 is easier to turn on and seemingly had a longer battery life Either way I still get great sound with this mic while converting it through a mixing board.
