I am rewriting this review as when I wrote it I had no idea what I was talking about.
 
 
 
Durability/Design
These cans are made of very brittle cheap plastic that could snap easily. This is constantly reminded to you every time you move your head as these tend to creak. I have heard countless stories of them snapping. But at the same time the design looks really sweet. With a silver/black color they are very visually appealing. I also found that the ear pads get cracked and broken really fast. Luckily it comes with a set of spare pads. The detachable cable is very much appreciated.
 
Comfort
My biggest complaint with these headphones is the comfort. They are very tight on your head and the ear pads are round instead of oval. This causes discomfort. I found my ears became red after a good hour of listening.
 
Sound Quality
These are good cans for any basshead who can handle poor build quality and discomfort.
 
Highs: Extended well and slightly harsh. But they are rich.
Mids: Slightly recessed. Still Holds many details.
Lows/Bass: Over emphasized to the extreme. Reaches low into sub bass territory. Doesn't bleed into the mids. And is very Musical.
Soundstage: Decently large for a closed bassy can. Things sounded like they were happening around me.
Speed: Fast bass response.
 
Preferred genres: Electronic, hip/hop, bassy music. Plays Heavy Metal really well.
Not good with classical or jazz or slow rock.
 
Amp is recommended
 
Final Thoughts:
These are good just be prepared to use the warranty in the 2 year period.
 
 

Pioneer SE M390
 
Durability/Design
The Pioneer SE M390 is a budget closed back headphone with an MSRP of $60. This remains as my first venture into higher end audio. Being 1.5 years old you would expect some wear and tear and probably broken headphones at this price. But alas it has survived being thrown around, dropped, even a car crash(I wasn't driving). The only wear i see is that there is some chips in the plastic above the driver where the 2 arches arch over the headphones. Also it has a piece of fabric that keeps the headphones in place which is all crumpled up and has pieces falling out. Worst yet it has become hard making it slightly uncomfortable. Finally the jack has had some shredding issues but it's not in any way that prohibits usage. A little electricians tape fixed it.
 
 

 
 
 
 
Sound Quality
Yes here we go. your all wondering what these sound like aren't you? Well now you find out. If I were to give you an example of a pair of headphones that sound like these I will say Beats Studios with more bass. Yes I said it, $60 for a similar sound signature to the Beats Studios with more bass. Then again it's not really more bass but bass that reaches lower into sub bass regions. Beats Studios don't do that.
 
Mids: The mids are masked by the massive bass of these headphones. It can make vocals and guitars hard to hear or make out.
Highs: The highs are recessed and laid back. not up front or enjoyable at all.
Bass: If you want bass look no further. I give you bass champions under $60 (The Sony XB500 may have more bass but I haven't tried them).
Speed: These are slow bloated bass monsters
Accuracy: These are not very accurate but are perfect for masking out bad sounding recordings. Anything will most likely sound good with these.
 
Amped Performance
I found when you amp these They gain a bit of a bass boast. I still don't know weather this is good or bad. It depends on who you are. But overall are very efficient.
I used both a Fiio E7 and Fiio E5 to test this.

Final Thoughts
If you want very bassy headphones under $60 these are a safe bet. They won't dazzle you with details but they are definitely fun. But they will only work with slow bassy genres like Hip hop and electronic.
