Pros: Sound is literally perfect for DJing, incredibly travel ready, durable, packed with DJ special features, unfairly cool looking
Cons: Can by harsh on ear cartilage if worn for long period, high price tag, that famous "big red B"
Wow, where to even start with the insane, surprising, and amazing looking package that is the Beats Mixr? Well I'll start by saying this: these are headphones exclusively for DJs and people who are going to be listening to music that has been created using electronic rhythms or beats (house music, trap, dubstep). That's IT. If you try to listen to The Beatles or Arcade Fire on these your ears will puke. They're just not for that. These are headphones made for the sole purpose of listening to and DJing electronic music. However, if that's what you're in the market for then whoa boy Dr. Dre and crew have cooked up a delicious treat that you can't help but fall in love with.
I am a DJ. I've been a DJ for many years now and so between mixing tracks in my studio and DJing live, headphones have become very important to me. The Beats Mixr are some of the best DJ cans ever made. Yup, you heard me. Despite being made by the same company responsible for the sonic atrocities that are the Solo HD, and the 250 dollars over price Beats Pro (fun fact: in my opinion the Mixrs actually sound significantly better than the Pro, even for the most "hood" of all trap and rap music) these cans are a really high quality product. Everything from the travel ready hardcase and fold-up design, to the coiled cord and 1/4 inch adapter that comes stuck on them are design to make life as a DJ the best it can possibly be. Plugged in to the super high-performance sound card of the well loved Traktor S4, they sound detailed enough to pick out every little subtlety you want to hear to be immersed in your mix, while bringing the backbeat and percussion to the front, making beat-matching a breeze. The flip up cans are sort of fun and certainly make one-ear monitoring easier, something pretty much every DJ likes, as well as giving it the ability to fold up into itself for travel; a useful little feature. Oh and the design? Look up any picture of these cans (I have the green neon edition, which seems to pretty much catch the eyes of everyone in the room when I walk in) to see how insanely sporty and cool they look. These cans have also gone for a design that hinges more on metal and tough, road ready plastics that give this can a vast amount more durability than anything Dre's brand has every put out in the past, ignoring the Pro, which pretty much has build quality as it's only advantage.
As far as cons go, they are certainly a bit bass heavy, but honestly these aren't trying to be audiophile headphones, they're trying to be DJ headphones and the audio curve on these is PERFECT for that sole purpose. The only major con I can come up with about this headphone is that they can hurt your ears after long sessions of use, but this is only really an issue when listening to music casually, as when DJing you really don't notice, and can overlook this easily considering how much they stay on your head no matter how into it you're getting while mixing. This is great for me, as I like to really headbang and jump around on stage a lot to get the crowd hyped. These headphones really don't have any flaw, other than being associated with one of the most controversial headphone brands in the world. They easily jump to the front of the pack when compared against Denon's options and go toe to toe with the other DJ headphone greats such as the V-Moda M-100s and the Sennheiser HD25 DJ Headphone (which beats blatantly copied many aspects of, but who can blame them as the 25 is clearly the headphone to beat when it comes to DJing). The Beats Mixr truly are legendary headphones when it comes to DJing, and I highly recommend them to all DJs if you're willing to pay a little bit more due to that ever present B.
