Has 3 prefixed gain settings (switch on the right hand side) which you can then fine-tune through the control panel when getting a level.
On one occassion when recording I was concerned about road noise outside, but through the headphones I could clearly hear birds twittering! (did I mention that you just plug in headphones directly?) No birds were in sight.
When making Embers I had planned on doing lots of foley sounds, and recording these myself for the first time. In the end it wasn't really necessary and the only sound that I recorded was the rain at the point the girl is inside the greenhouse. That was a very rainy day last November when I opened the front door and just let the H2 record whatever it could hear.
I have no idea how the H2 compares to the other mics you're considering. What I wanted was a mic that didn't sound like a gaming headset (popping, breathing, etc.) and would be super-portable so I could go to my voice actors, set up, record, and do this with minimum fuss.
(BTW. I've never used noise reduction in my sound editor for anything that the H2 has recorded. )
Wow, that puts a lot of concerns to rest. It's great to know you weren't in necessarily ideal conditions when laying down the VO's. As I said before I love the idea of being able to record my own ambiant tracks. I think I'm pretty much decided I am going to purchase the Z2. Thanks for the reply!
