I look at it like this, just like the many zombies that purchase Beats because Dre, Lebron, Nicki Minaj, their friends, etc tells them to, I see it the same on Head-Fi. Because these self proclaimed audiophiles say Beats sound horrible and are overpriced, everyone else on the boards follow suit. It's funny that each side calls the other stupid. Talk about the pot calling the kettle black LOL.
Anyway, I see Beats like I do pretty much all other headphone companies, they have horrible cans, great cans, and overpriced cans. I've spent much time with many of the Beats headphones, not just listening for 5 mins in Best Buy and parroting what I've read. My take is this:
Beats Solo HD - The worst of the Beats lineup in my opinion. Very muddy, and lacks detail. The Soul by Ludacris SL150 really put these to shame.
Beats Studio - Very bass heavy, warm mids, and decent highs. Worth only about $200 in my opinion. Don't sound bad though.
Beats Mixr - One of my favorites in the Beats lineup. Has the most detail of all the Beats cans. Very fun sounding. They are uncomfortable though.
Beats Pro - Very good as well but not $400 good. Same sound signature as the Mixrs with more Bass. Only problem is, the Mixrs are $150 cheaper.
Beats Executive (NEW) - These are probably my overall favorite Beats Headphone. They are basically an improved version of the Studios. They best the Studios in noise cancellation, sound leakage, sound quality, and build quality. They're built like the pros. The bass has been toned down on these and the mids brought forward. Far more detail than the Studios and have a tighter/cleaner bass. They are also very comfortable which is why I give them the edge over the Mixrs.
Beats are not bad in my opinion and they have their place in the headphone market.
