Sound Quality: I don't go into much detail here, besides mentioning the obvious. First, they're very warm sounding headphones, with a good bass abundance. Perhaps not as mind boggling as some headphones from the Sony XB line, but can have a lot of power. The bass is one of the biggest aspects of the sound signature, the mids are also nice and warm, not receded, the highs are good and avoid being shrill. The soundstage is pretty wide for the design of these headphones, and while I have headphones that sound better for music, these are my headphones of choice for gaming and movies. Sound isolation is not one of the highlights of these headphones, since they have a semi-open design and can also leak sound to the outside. I have no tested to what extent, but blasting music in public with these headphones may not work out well.
 
Design: Only quality $30 headphones have good design. Many headphones of this price don't take full advantage of their price, but these headphones do well here. My only complaint is the ear cups falling down when not supported. This doesn't help me much, since I like to hang up my headphones and this can get in my way. Other than that, they are still built well and have a sturdy design. Not very portable, however.
 
Comfort: I was pleasantly surprised with the comfort of these headphones. The artificial leather pads are surprisingly plush and comfy. I am not used to "plush" headphones, and these are easily more comfortable than my Sennheiser HD 25-II's for long-term usage and more soft and padded than my Shure 750DJ, making them currently my most comfortable headphone! Comfort is not a worry with these headphones, though they may not be quite as soft or comfy as some of the Sony XB line headphone pads.
 
Overall, I was very impressed with the performance, comfort, and design of these headphones, with only minor gripes that come with owning more expensive headphones and trying to compare them with these. Still, they managed to best my other two in the Comfort department.
 

Amping: I disagree with the idea that these headphones require significant amping, as I use these out of my iPod and laptop all the time and, while amping would be a nice addition, certainly run fine off of an iPod. They have very nice bass quality, and enough quantity to give a head-rattling when properly EQ'd, while not as powerful as the XB500's.
 
Music Genres: I find these headphones best suited for electronic, dance, and hip-hop music genres, as well as music that doesn't focus highly on acoustic sounds. While I do listen to rock music with these, I found that in comparison to a headphone like the Ath-M50, they couldn't truly produce the same shine in the genre.
The midrange is somewhat lacking in these headphones, and possibly the most neglected of the spectrum. Highs are good and have precise detail, but the biggest focus in these headphones are certainly the bass; they are very quick to catch the beat in even the fastest techno songs. The soundstage has a good size as well.
 
Design/Durability/Comfort: These headphones are very durable and can take a lot, at least in my experiences with them. Their plastic design may seem cheap and delicate, but I disagree. And also, since you may be considering the purchase of these headphones, I will inform you in advance that they do come with a very nonspecific State of California Warning, which I can only presume has to do with a possible chemical treated on the white plastic parts to ensure durability (as long as you are not trying to ingest your headphones, I wouldn't worry too much). While I'm not a fan of bad chemicals, this was added most likely to keep the plastic from cracking or breaking. The plastic can creak when you are moving around, but stationary I do not find it very noticeable.
Most people say that the Shure headband design is a "hit it or miss it," so if the headband doesn't work for you, it may not be a good idea to stick with them. The adjustment sizes can also run a bit small, so if you have a fairly large head you may want to try these on before purchase.
While not the most comfortable, I can wear these for hours without any real pain or soreness. Kind of like a basic bed, it provides decent sleeping conditions but isn't overly plush or makes you feel like you are sleeping on a cloud.
 
Portability: For a while I used these for portable, on-the-go scenarios as well as at home. The leather pads (not sure if they are authentic or PU) can get hot easily if you are not in an environment that is below about 80 degrees F. This may be a redundant remark for most, but living in Florida if you aren't in a place with A/C it is probably not a good idea to use these as they get very hot and stuffy inside the ear cups.
They are also bulky and, as I mentioned previously, the plastic can creak. While the style of the headphones is pretty nice, they are a little big to be wearing in public unless you don't mind. I am not using the Sennheiser HD-25-II's for portable use, and they are much better for this purpose. However, I am not as big of a fan of the sound signature as I am of these, and cannot wear them for as long of a duration.
 
(Not being a big audiophile I did not want to go into much detail on SQ so as not to give people any wrong impressions.)
Oh and sorry for accidentally uploading that picture of them on the banana stand... I didn't know it would make it the main picture.

Now that I've sold these headphones and traded them in for a pair of the Shure750djs, I will now go ahead and give you my comparison between these too and how these headphones are lacking in general for price.
 
Value: I bought my Srh750's for $108, their retail is around $150-200. The HD's are $180-200. The Beats headphones are better than a standard low quality pair of headphones because of their bass, which I feel is not the greatest quality but VERY apparent. It is how buyers are lured in, especially those who had the Apple earphones with no physical bass at all. I think buyers catch what I will call "bass obsession," where that feeling of pumping bass is so new and powerful they simply can't resist! On top of that, the brand name, portability, and styling catch their eye, and next thing you know they are ringing it up in the check-out line without any forethought on other headphone possibilities. These headphones may be a decent alternative for Skullcandy's, but just remember what you are buying when you buy these headphones- it is not the sound quality.
 
Audio Quality: While I owned these headphones and had little experience with quality sound, I did still  notice the drowning bass. I once turned the EQ on my iPod to Treble Boost, and I heard a horrid, painful, spikey treble. Imagine someone poking your ear with a little needle. It caused my ears to be very fatigued quickly, but as soon as I turned off the EQ the bass suddenly drowned out everything. It was like I threw a pillow at the singer's face and tied it there for the rest of the song! These headphones are very lively in term of bass, but that is about it. The bass is very unnatural and lacks variety and depth, which is something I instantly noticed with my purchase of my other headphones. Once the customer overcomes his bass obsession and looks for finer sound quality, or runs across a pair of Sony XB500's, for example, he/she will leave these headphones in a second.
 
Design: These headphones are flimsy. I do like the sleekness and thin design for portability, but it wouldn't take much effort to snap the sides. They are very easy for around-the-neck carrying, and unlike my new, large cupped headphones which feel like a neck brace and seem abnormally large around my neck, these are pretty comfy. However, I found that my hair caught caught in the headphones a lot, which shouldn't be a problem for men, but women may occasionally have to yank a strand of hair out of their head when they wear these headphones. I would like to say that if you want to buy these headphones, you are mainly buying them for their design and brand name. If you want anything else besides mediocre sound quality, don't consider these. The build isn't great, and for those who aren't careful or all too used to their indestructible earbuds, you will likely break these quickly. However, their exterior styling is unlike many headphones currently on the market, and makes a great style accessory. I believe they look better on your head rather than alone; very low-profile styling.
 
Comfort: I am not used to comfortable headphones. I have never owned a comfortable pair of headphones in my life. With this said, I would still complain slightly with the long-term wearing of these headphones. Many say these headphones are very plush and comfortable, but in my case it is only temporarily. This could just be a personal discomfort, but it is very predominant after some time, so I thought I'd mention it anyhow. Wear these headphones for more than an hour, then remove them. I find that I don't notice the soreness that much till I remove them. Then, a painful soreness shoots through my ears and I never want to put them on again. Obviously, this is a fault of the on-ear design. My Shure's are also uncomfortable, but I can wear them for hours and not worry about any pain (over-the-ear headphones). One fault with over-the-ear is the fact that if you own glasses, you can't really wear them with them or have to skooch them up a tad, but that's besides the point. On-ear typically become uncomfortably after an hour or so of wear, unless you have a notably comfortable pair. So in the end, these are short-term use headphones, because you'll need to give your ears a rest not just from the sound but from the pads too. In the short-term, however, I will agree they are quite smug, and noise isolation is surprisingly impressive!
 
Overall: Not worth it. If you are on head-fi, you shouldn't even be looking at this review! You should be asking around about a real pair of headphones, because that is what the forum is for. If you're going for design, go to a Best Buy or electronics shop and look around, because it would be a waist of time if you looked here. Most of our headphones look big, mushroomy, and don't have well-known brand names in the "trendy" department. If you're buying headphones to impress the people walking by you, these are pretty good, just don't have one who knows sound quality try it on.
