Have you guys seen these in the wild ? It's either the best thing since sliced bread, or the worst headgear you've ever worn, I can't tell by looking at it. They are passive, and a little strange looking. But if this is function over form, they could be a cut above. I can't find any reviews on the internet, maybe that's a clue. I dunno.

I am looking for some ears that will offer actual sound ,
Not muffled,
But volume controllable .

To attend concerts but at 50% volume.

Plugs or muffs have a lousy effect .

I was comparing this model to other passive muffs, not modern electronic protection. Passives are still the best for the worst sound impact environments. That was the point. Of all the passive models on the market, these look different than others, and given the reputation of the company for sound protection and the complete lack of hits for this model on the internet, that's why I was asking about this model.

Has anyone seen it before ?
