No because I want decent sound so play through my hifi, not some dogshit headphones. The same fucktards that buy "gamer chairs".
What the fuck are you smoking, almost all extreme high-end sound configurations involve headphones. Audiophiles frequently consider a good set of headphones vastly superior to a good set of speakers.
No they don't, either you completely made this shit up or you live among poor or dumb audiophiles who can't afford to create a good speaker system.
Headphones have their uses (I'm using a pair right now) and it's true you'll get better and more detailed sound for cheaper, plus you don't need to know anything about room acoustics, but they're always a compromise.
- In the bass region you don't just hear with your ears but with your whole body (your skull but also your long bones act as a conductor). This is very apparent during loud concerts, but it happens on normal volumes as well. That's why some people prefer a lot of added bass in headphones to compensate, but that muddies the sound.
- Due to various consequences of the headphone being too close to the ear (like the wavefront having a completely different shape compared to a loudspeaker or real sound, often it also differs headphone to headphone) the transfer function of your ear is different than when using loudspeakers. This means that headphones which sound neutral and realistic will not have a flat frequency response, the response will look all fucked up, in contrast to loudspeakers. The issue is that this desired frequency response is different for each person and slightly less also for each headphone. This means that truly precise headphones with perfect frequency response do not exist and you may only get close by chance. Unless you have your ear's transfer function measured and EQ your headphones based on that.
- For similar reasons the auditory illusion of the musicians standing in front of you can never be that great: the sound does not realistically interact with your room, the image moves with your head, the sound is not coming from the front but from the sides etc. The fact that 99.9% of music is mixed and mastered for loudspeakers does not help either. Binaural audio bypasses this, especially when using in-ear headphones. Except that the previous issue of each ear having different shape still exists and binaural recordings are made with an "average ear" model, so you'll get slightly fucked up spatial clues, slightly fucked up frequency response (this is more audible and more common) or both. Also you cannot transform existing recordings made for loudspeakers into a binaural version.
There are other issues, but these are the main ones. Some of them will get solved with more technology, possibly soon, but they're not solved now.
If you take loudspeakers with smooth frequency response and +-constant directivity and put them in a room with some acoustic treatment (not even that much if they're not wide-directivity), you'll get actually impressive and realistic sound with none of those issues. The only exception being bass, for which the acoustic treatment is pretty expensive.
For the record I'm not an audiophile, I'm just a guy who's been building loudspeakers for years, on occasion commercially, so one of the main things I've been trying to learn over those years is to recognize stupid nonsense and find the things that actually make a difference in sound.
