Question: Also, how would you rate the bass?
Document: The cord is a bit thicker and is the same even where the wires "Y" whereas on the S4's the wire thins out. They also produce the most volume by a good margin so if head banging R&R; is your thing, I would think they would fit the bill just fine.One more thing for those wondering what's in the package. S4's have 3 sizes of earbuds and a carrying case. Not to be outdone, the XX have 3 sizes of earbuds and a case too. The AT's have a 1/4th" adapter plug.To summarize, I'd rate them as follows.Sound quality:  1st place goes to the S4's, 2nd to the AT's and 3rd place to the XX'sVolume:  XX's, S4's, AT'sOverall:  S4's, AT's, XX's.
If you love acoustics and things like that, this probably be your best friend. If you're looking into heavy bass like Beats, then you probably want to look somewhere else. I would rate this a 3 or 3.5/5. I will update this review later this month to see if I have a different opinion. *UPDATE EDIT* I've had it for almost a year now, and it has improved drastically. The trebles, highs, and vocals are still crystal clear. The bass has improved a bit but still not comparable to the Beats.
ill have to update in this week after the 100 hour mark with pink noise running every night for 8 hours at medium volumes.EDIT #2:  Two days later: Mids are finally coming forward. Enough for me to rate it a 4 star at this point. Ill still leave it here at three so people can see why I originally put it at three. Still a little too strong of a treble emphasis, but the detail is also more present now. Now the mids are at least there and the treble has calmed itself.
I rarely rate products, however I am very impressed with these headphones! I consider myself to be a bit of an audiophile- I've owned headphones from Bose and Klipsch, which were significantly more expensive than these headphones.These headphones, unlike Bose and Klipsch, really strike a balance between bass and treble. For around $38USD, I really can't recommend them enough.
The wife bought it off of my wish list. Hey whats better than getting something you already want. Its great. I'm a low rate sound man and I may not have the best hearing, but these headphones rock my world for the price. Sure you are not going to get the same stares from the non-audiophile beats wearing peeps. But you'll know what your hearing. Not pounding bass , but a full range of sound that is candy for the ear drums.
I also have to expect my work to be played back on sound systems at stadiums which tend not to have a lot of bass sometimes, so it isn't necessarily a true representation for me. However, if you are buying them just to listen to your iPod through a good set of headphones, these are perfect. They are very comfortable up to a few hours, and after that, I think just about any headphones would be annoying.
I  received these headphones a few days ago and theyreally pack a sound punch. Excellent clarity,volume,bass, high and mid-rangesound. Studio quality phones .They are also very comfortable and  easily adjusted.The included adapter is also a plus.I would recommend them for any use ,studio or otherwise.Very nice product.
I would like to say for the price you are getting great quality headphones. You can hear every detail clearly and the bass is also great.Only bad thing about these headphones is that after wearing for hours it starts to feel tight and hurts a bit. Also many people complain about the pads but mines have not fallen off yet. Good sign. Great addition to my studio.
These head phones are simply Amazing! After reading all the positive reviews and looking at some other headphones. I decided on these, and they dont dissapoint. The first song i played when i got these was a techno song, and i gotta say the bass in these headphones are pretty good. They also sound great with all types of music. I would definitley Recomend you get these, and for only 40 bucks, you cant beat that price.
The cord also has a spring on it at the end, probably so that the cord doesn't bend to much and get ruined from the metal of the jack or something, which is also very useful. The sound quality of these are amazing compared to what I have used in the past, crystal clear audio as far as voices and instruments and what not, however the bass is almost non-existent, so if you listen to bass heavy music, then these aren't what you would want to be wearing to listen to that kind of music.
Answer: The bass is fairly strong and tight, not at all boomy, though not the best I've heard.  Definitely very, very good for this price range.
