If you're looking for a complement to the Beats, I'd recommend the Sony V6 or 7506. They have a slightly emphasized treble, while having accurate everything-else, and also have a lot of detail.
I've got to play with these now over the weekend, and I must say that I am impressed. Thanks RPGWizard for "sponsoring" me (he bought the cables, I kept the headphones. I'm using them with a Monoprice retractable 3.5mm cable). Overall...
Well, not to post a scare or anything...but in the spirit of transparency, Monoprice did get hacked about two years ago and customer info was compromised. I personally was a victim of credit card fraud because of that. HOWEVER:

I've tried both M50's and D1100's (and sold one of them) - if they are in similar price ranges, I would prefer the Denon. Better fit and sound for me. I'm assuming you are looking for a warmer sound?
I agree with many points to the article. I was not aware that a "new" version was out, though. I bought a pair in 2009 for $80 or so, and was shocked to see prices skyrocket to $100, and then $150.
The M50's still sound...
I have a problem with the answer choices. It's kind of a loaded question and anyone on Head-Fi would choose option "bottom-left."
I don't believe they are high-end headphones, but they are definitely steps above the ipod...
Audio Technica AD700, Sennheiser HD448, or the older HD555 (if you can find it new for less than $100..) are good choices to start.
I also really enjoy the Denon D1100, although it does color the sound, it makes classical...
