Summary: *Note I did not purchase the one with the microphone
Right after I got my Beats Studio stolen, I decided to get a temporary pair of headphones while I get better ones and these seem to be great for that. They come in a tin carrying case (somewhat cheap) and come with medium, large and medium double flanged tips.
Pros: Above average bass response, price is just right, great isolation, lightweight, overal clarity
Cons: The treble may sound fuzzy, to me it did, cheap carrying case,
Summary: For $100, I am completely satisfied with the earbud's comfort and fit in my ears (guarantee one of the three sizes will fit), the sound quality (compared to so many headphones at the $200 range, including Beats by Dr. Dre at ~$300), and the controls (now I use the Galaxy S2, only the middle button works).
Summary: Let me just start of by saying these headphones are great (for the price). They fit well which is rare for my odd ears and really have excellent noise isolation. Again for the price range.
My one complaint is quality. These are not something for a commuter or jogger etc. These will break if you don't hold them in silk case carried by a man who can't move. The first one I got shipped broken. Left ear did not work at all and the microphone button didn't work.
Summary: I bought these alongside the UE500, with the intent of keeping the one I liked and returning the other one. Auditioning through a stereo, the S4s were a little less lively and smooth than the UEs, and tended towards some fairly bad sibilance, especially on classical tracks with high violin parts that were almost painful to listen to. I liked the UEs better, and returned these.
Pros: Very comfortable, easy-to-use, consumer sound
Cons: Tends towards sibilance, better options for the price
Summary: I got these after I put my UE Super Fi-4s in the wash and I couldn't handle my cx-300iis not fitting quite right anymore.
The newer version has a straight plug, and a decently thick cable, which hasn't tangled, but it is quite bent fro being wrapped up. However, where the cable goes into the housing of the earphone, there is a slightly thicker part that wraps around, which has cracked after 6 months, and it sort of scares me.
Summary: Audio quality-pretty good. Bass can be overbearing.
Design-it is comfortable. Sticks out at an odd angle if you don't swap ears, and then the stereo is reversed.
Comfort-As above. Don't notice it in my ear with the Comply TX-100s I added. With silicone it can be annoying.
Isolation-Pretty good with silicone. Awesome with Comply.
Summary: Hmmm... I did a bit or research before buying these. There were plenty of glowing reports out there and the cynic in me thinks that most writers on major sites write nice reports in order to not bite the hand that feeds them.
The build quality seemed average at best,
the cables transmit a lot of noise, it like someone running alive mic over clothing
The mid range and treble sounds like its coming down a phone line
After 6 short months of 1-2 hours use per day...
Pros: reasonable bass
Cons: poor build quality leads to short life span, weak midrange
Summary: I bough them to a friend as a birthday gift the last year. He tells me that are excellent headphones, perhaps to not make me look bad or maybe he was right, so I decided to buy my own pair. just as a note I bought my friend's S4 twice of the price than mine in a music store in Mexico, so the price varies too much in these latitudes.
It not brings you any extra for your money, only three sets of tips that aren't so useful.
Pros: Good design, good deep bass, isolation is very well and can be worn for a couple of hours without any discomfort
Cons: Few accessories, tips have unhelpful core diameter, the cable collects noise and looks fragile
Summary: These were the first IEMs I bought that were over 50$ after reading good reviews on it. Unfortunately I don't think they live up to the hype. They are definitely better than some of the other consumer-oriented brands such as Beats, Bose, etc. but they are not worth 70 or 80$.
Note: I do not have my fully functioning S4 anymore because I recently lost it. (long story) The one I mention in this review comes in the blue CNET box (no cleaning tool, straight plug).
Pros: Good overall sound quality, nice aesthetic design, one of the better "consumer" headphones you can buy at retail
Summary: I received these headphones for a Christmas present after doing A LOT of research. I enjoyed them at first, but after less than 3 months the cord at the jack began to loosen, even though I religiously put them back into their case after every use. By the time I had owned them for 6 months, they were no longer working.
This part of the headphone is not covered by warranty, so I no longer have the headphones, or the money.
