Huge on my ear flops everywhere but volume amd quality is amazing very good quality if it wasnt so big on my ear
Great product it’s the second one I had. Wearing hearing aids is difficult in my job. this gives me the opportunity to listen to transmissions at the right time excellent product.
I use this when I'm working off duty at concerts, works great
