I thought they were a gimmick when I saw them on social media. My daughter bought them for me for Christmas a couple years ago and I have been surprised. (I don't know which Axil GS I have)
I used them last weekend in a 3 day field match; In this match you RO the guy behind you between hikes, and I saw the guy i was RO'ing the second day didn't have a suppressor. I used these and while i didn't use the bluetooth option, I ended up forgetting I was wearing them. Usually I just put the ears in when I RO a boomer, but I forgot I had them in (i shoot suppressed) and found them very comfortable. Battery made it for about 8 hours of field courses, and is still operating.
