Headphone systems, just like conventional systems also have many level of sound quality and price.
Although it's true that a smartly put together headphone system can sound very respectable with a minuscule investment compared to a conventional system.
In my experience, my headphone system is a highly modified Headroom Max with AKG-701s, when state of the art headphone performance is maxed out, a very high level conventional system can and will continue many steps beyond in realism and overall performance.
There are also a number of things a conventional system can do that is simply not possible for headphones to achieve.
Examples would be realistic visceral bass ie moving lots of air, and the interaction of the music with the outside environment, walls carpet etc. The same interactions live music goes through.
As good as headphones can sound, they're still far less representative of real music than very good conventional systems.
