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.
