Let me just start by going over pros and cons and then I'll go more into detail afterwards.Pros:-Amazing sound (rich lows, sweet highs, etc.)-Lengthy cord (over 11' long)-Lightweight-Comfortable for long periods of time-Arrived a day earlier than expectedCons:-Lengthy cord (over 11' long)-Large and cumbersomeAnd now for the details:I am a music major in college. You know, the people that spend all their time playing music, messing with soundboards, listening to and analyzing everything, etc. The stereotypes of music freaks are there for a reason. So I decided that I needed to get myself a good set of "professional-level" headphones. I did some searching, went to local stores and got nowhere. So I switched to online searching. I came across these headphones and I'll admit, I was skeptical when I first ordered them, but I'm glad I did. As soon as they came in the mail, I took them for a test run on the first thing I had access to, my iPhone. Sure enough, they were phenomenal! I was hearing things that I never knew existed, the bass was incredible, and the higher pitches were flawless and clear. I instantly realized that I was glad I got these. In fact, as soon as my brother saw them, he pulled up a list on his computer of the best headphones to get, according to people online. Sure enough, these were right on that list and I didn't even know about it!The only bad things that I have noticed are very minor. They tend to stick out from your head, even so much that my parents say that I look funny when wearing them. But for the sound that these offer, they are worth the look. But they are also large enough so that is it hard to carry them with you. Thank goodness I have a large laptop bag, or else I would have to figure something else out.I listed the length of the cord as a pro and a con because that is just a matter of perspective. Considering that I am a music major, I like the idea of having a long cord that will give me freedom to move around the dorm room while still listening to what I need to. So it is a pro for me, but not necessarily everyone.They are extremely lightweight, or at least I think so. The only weight problem that I have noticed is that when I tilt my head downward or upward, gravity pulls them to the ground so it puts pressure on my ears. But other than that, they are so comfortable that you will forget that they are there.And now for the sound. Some reviews have said that these headphones take time to wear in, but I guess mine must have been made just right because I am not noticing a difference over time. Either way, the sound is great. Every note in the base line is clear and audible. The runs in the upper range are precise and sound incredible. Everything else in between is much better than I expected by a long run. So if it is sound you are worried about, don't be worried in the slightest bit.In conclusion, if you want great headphones for a cheap price, go for these. Seriously, don't look any further, it will just cause stress. I've posted a picture giving details on what they look like compared to my hand and little things like that. Check out the picture, check out other reviews, but trust me. You can not go wrong with these headphones.---EDIT---I forgot to mention that they are not soundproof. In fact, right now I am listening to music while listening to my parents talk about our dog and reminiscing about old movies! The good thing is that the sound is still very clear and the outside voices are muffled. I can still clearly understand if someone wants my attention, but I can listen to music and whatever else I need to at the same time. So this can also classify as a pro or a con, depending on how you personally work.
