Love the good hearing protection with the abolith to listen to my music at the same time. Truly fantastic.

I wear these as secondary protection over silicone / custom fit ear plugs at annindoor range. I like them. They could do better at conveying voices in busy environments, as with 7-8 active shooters at the range… no bueno.

Not as quiet as I expected
I am sure they are working as designed but coming from 3M Pro grade $35 muffs rated for NRR 30, I found these do not perform as well in terms of lowering the noise at the range. I guess that is the difference between NRR 30 and NRR 25. But having the ability to communicate is a must so I’ll make due. Next time I’ll try adding in ear foam. The controls are good as is the comfort and I like the same ergonomics as my orange ISO tunes in the shop.
