what Ferrum Master say is professional and experienced, I would like to add that besides the problems you will not like what they sounds like, the sound it will feel wrong to you, waveforms are not intended tobe heard as they are, the distortion of conventional speakers is absolutely unseparate part of the production process, nobody ever makes sound content movies or music vinyl or cd, for electrostatics
oh one other thing to add, electrostatics don't work on low frequencies, there is some danger that may cause short circuit, so there is a high pass filter at about 100 hz or so, so you will need a classic subwoofer with them
I've enjoyed the presentation of them every chance I've gotten. I don't care that stuff is or isn't mixed for whatever I'm using - I really don't see a meaningful way for anyone to reasonably do that, so I just worry about if it sounds good to me. Electrostatics tend to have this almost ethereal quality, this fineness that just is not remotely like anything else. I can get things out of that. I can enjoy the same music in an entirely different way. It's definitely not what I would call 'natural' and more like 'so real that it slips into unreality'. But not nessesarily uncanny. It's not jarring to me. Takes a minute or two and then normal headphones sound weird to me, and the electrostatics sound right.
Death of the author and all of that. Once you put your production, your work, out there for people to consume... those people will pretty much treat it as suits them. This always has to be the understanding, the expectation of the producer, that he cannot account for everyone's listening conditions. They'll be on their own with it. That doesn't make it necessarily wrong. This does not mean disregard all expertise, but also do not disregard your expertise in your own experience... within reason. Because there are magic rocks out there for people who trust their experience a little too much too. But basically, if the guys in the studio did it this way, but you like it better that way, do it that way! Like, why ever would you choose the option you like less? I need for there to be a better reason than authorial intent here, it's not enough. It doesn't make any sense, from an appreciation standpoint. You lose enjoyment of the art to that in too many cases. There's plenty of room for preference in all of this. Studio technicians have as many preferences as the musicians they record. It doesn't mean that the audience will always agree with their sensibilities. That's a total coin toss.
I mean, there are piles of crap mixes out there that will sound good on the 'wrong' gear and bad on everything normal. Again, how is one to reasonably account for the whole range of sensibilities and techniques of every different producer across genres and eras? That just sounds like an utterly psychotic preposition to me. Don't wanna be harsh but it actually makes me laugh to think about it, just on the amatuer side, learning how different producers do it... and more importantly, what they go for and why. So many schools of thought and different ears intertwining. I would never wish to go down that rabbit hole. I could already be enjoying the music.
Of course low frequency extension is out, that's the price you pay for the distortion characteristics and mid-high frequency behavior that give them their characteristic sound. They are also more delicate. Don't be a dum dum and EQ the bass up 6db. Care for them. Lets also not pretend like they are squeaky clean. You're not getting 'pure' sound out of them any more than anything else. It's really all flavors with headphones. It's just not normally how we hear things. Right from the get go you've got drivers strapped right to your ears, messing with the interactions that usually help us make sense of things. The whole experiential package is a totally different construct from speakers, which are also quite different from live sound.
I'll put it this way... all headphones sound like headphones to me. At no point do any of them transcend that. That is to say coloration of all manner is a given. It's just a matter of the compromises taken in the design. The physics are what they are.
That's just me, maybe I'm just more easygoing with things. It's all just a wider range of experiences with music to me at the end of the day. I value that a lot. It's cliche but music really is my drug. My brain doesn't work like most peoples. They even checked! Music does a lot for me in that regard. I don't see why this stuff has to be this complicated... have this many rules. You can just enjoy it.
