I actually use ZTac ComTacIIs, so I don't know if what I'm saying applies also to the ZSordins; take everything I say here with a wee grain of salt.

First off, I don't know how the sound-dampening works in them, because they sometimes mute stuff that doesn't need muting and amplifies stuff that doesn't need amplifying. For example, my headset particularly loves to mute doors slamming. Even closing a door extremely softly, it gives the "click-mute" feedback of sound being dampened. I've then worn them while running a table saw and nothing is being reduced. I also used them on an Air Rifle range (earpro is usually not required anyway so I was like meh, I'll try) and it dampened the sound of the bolt closing, but not the shot being fired.

No real experience with explosions and really sudden high-decibel noises (table saw is more prolonged; might be why the headset didn't cancel it) so that remains to be seen.

However, amplification is good, and it's pretty much like normal hearing with benefits. A small static noise begins to creep into the set at higher volume settings, but you get used to that. People talking to you is clearly transmitted, whispers occasionally, and things like clothes brushing, doors closing, and floors squeaking are clear to somewhat less clear dependent on loudness, range, and obstruction.

I find that there's no real 'amplification' of the ambience I'm in in terms of if you suddenly get super tactical elite night ops delta cag hearing abilities; it's really like normal hearing, but sometimes you'll hear some extra stuff thrown in.

They're a great headset for the price, and it won't compare to the real deal, but it's definitely got a use for Airsoft. I haven't used them too extensively, but from what I've used them for, I've got a definitive tactical advantage (a small edge, but an edge nonetheless) from the non-dual-cup-headset inclined among us.
