i recently got warned about a beats discussion by mods. So they can be heated debates. I like the fact the beats exist, it tips that scale of being interested in audio is cool and fashionable, then its just a hop skip and a jump to caring less about what they look like and more on what they sound like.
Another factor to consider is if i am a person who can't tell the difference between beats and say m50's, im gonna pick the beats cause they look better. There is no reason to get the m50's unless i find the sound to be significantly better, and your general listener isn't a sound engineer.
