To start off I have to clarify that i am not an "Audiophile", nothing about me is audiophile related except the love of music and headphones. So to start this review i'd like to talk about the build quality; the build quality on this headphone is amazing, I'm very surprised the way beats by Dre designed this headphone, due to the history of "Bad Buid quality" that beats by dre has offered us in the past, but luckily this headphone is constructed out of very durable aluminum. I honestly don't have any complaints about the build quality of this headphone besides the fact that it scratches easily. So if your somebody that doesn't like their headphones getting damaged or scratched, then take into consideration that these will scratch easily.
Next i'm gonna talk about is the comfort, the comfort on these headphones is terrible; i can only wear these headphones for thirty minutes at most, since these are "Dj headphones" they have a tight clamping force which will hurt your ears, and the ear cups aren't breathable, so your ears will get hot, sweaty, and turn red. Even though the ear cups are made of memory foam and are good for adjustments I still need to take these headphones off my head after thirty minutes. Beats By Dre claimed that these headphones have an over the ear design; well in the long run they aren't, the ear cups have a circular shape so they won't fit completely around my ear, so technically this is an on ear design. Also these headphones wouldn't be very good D.J. headphones, due to the lack of isolation. These headphones aren't very good at isolating, they barely block out any sound at all, for a closed back headphone.
So whats a headphone review without saying how they sound? Well than that'd be pretty stupid, so lets talk about how they sound. So the sound of these headphones is a real disappointment, I'm not saying its bad, but its not good enough to be worth $400. The lows over power the midrange, and the high end. So this means that if you were to listen to any other genre besides hip hop, or electronic music; it wouldn't be an enjoyable experience, due to the lack of instrument separation. So This headphone will not sound good with rock, metal, jazz, or anything. The instrument separation on these headphones are terrible. the only thing i wouldn't complain about these headphones is the low ends, the low ends on this headphone is excellent. The treble on this headphone can be very harsh at some points in a song, it started to hurt my ears, i rarely ever listen to this headphone because of it.
Overall There are much better alternatives than Beats By Dre, there are much better brands out there for a MUCH cheaper price. Your not paying for quality, your paying for the name. I guess I'm just being nice by rating this headphone two and a half stars.
