Well yes. I try to clarify a little:
I'd like to be able to watch the movies I've just mentioned (and also add the likes of The Avengers and We Were Soldiers and so on) in a way, that is as good and loud and precise as a good sound system, but without the neighbors nagging me.
I like it when there's a chaotic gunfight in a movie, and I can hear not just the gunshot, but the shells hitting the floor, and maybe even hearing the distance and direction of the gunshots, if the movie's sound editing is good enough for this of course
also what I want during an explosion, the Transformers 1 Scorponok scene is a great example! When the shells from the AC130 hit the ground, or the bullets from the A10's gattling drill into the sand, these effects have a strong bass, that should not just be heard, but also felt punching you in the stomach.
So what I mean by immersion, is a type of headphone, that is able to give me back the authenticity of these scenes and effects, as loud and clear as real life would. As directors imagined them!
And all this goes for games as well
Also in We Were Soldiers I love how gunsounds are clearly differentiated, for example I don't have to see in the movie that they are firing M16s, the plastic housing can be heard in the sound, it has a high pitch. At the same time an AK-47 is very different stronger in the mid, with more metal sounds.
Open or closed not a factor. Usually when I would use these headphones there would not be people in the same room with me, no isolation needed. So which ever sounds better, is what I want
Price range is not decided yet, first I want to educate myself on the topic, but, well....
many people seem to like the DT990, which is about 50k Ft in Hungary, that's about 250 USD.
That is acceptable, maybe if the price/value ratio is good enough than we can go up to around 300 USD.
Your last question, the supplier/retailer is what I would like to consider as a step 2 of this project
Once I know enough and I have my eyes on something I figure out where to get it from.
