Hi, I'm a head-fier and I have beats. (It's like admitting you're an alcoholic). I have two pair of Beats Tour. And I even own a pair of Beats Pro.
The Beats Tour are fairly decent earbuds for the money. I bought them because of their comfort. I used to love the Shure EC-4s, now discontinued, and the Tours are the nearest replacement I've found for comfort. They don't need to go deep into your ear (which really annoys me) to get decent sound, and they are very good for watching a movie on the road because they rumble nicely.
I purchased a back-up pair online and they were definitely fake. The sound was similar to what you would hear out of the $2 dollar airline earbuds you can purchase during your flight. The box was such a good replica, even the packaging and tips, you would never know they were fake if someone just gave them to you. And I suspect many people who bag on Beats were likely listening to a fake pair.
Now I will admit, the Solo and the Studio are pretty darn awful. I can't imagine wanting a pair-- ever. But the pros aren't bad-- but they are extremely overpriced. I would put them at the $200-$250 range in sound-- and they have a tight clamp which gets uncomfortable after an hour or so. I bought them to hear what all the fuss was about. They deliver loads of bass and average highs, but they are clear and make decent sound. Not great sound, but good. I will likely be selling them off within the next month or two because it's a lot of money to be sitting around not getting much use.
But I will hold onto and continue to enjoy (yes, enjoy) the Beats Tour. I also own RE-0 HifiMan, and they sound better, but they bother my ears after an hour. The Tours don't bother me even after a two-hour movie. I also own customs-- UERMs, which, naturally blow both of these buds away, but they're a commitment to wear (though I do commit often).
But I don't see Beats as the "evil one" as many do around these parts. The Tours are decent.. The Pros overpriced.. but they don't sound like garbage. I don't see a big fuss.
