These were my first phones that didn't come with an iPod, and I will say that when I got my first pair about three years ago, I was amazed that music could sound so good. After a few years of experience, I think I'm a little more qualified to write a review.
 
First of I will say that I would reccommend these to anyone as their first IEM or headphone on a budget. I mean I can get as nitpicky as I want but they sound good, as I do love bass over anything else. From a more professional standpoint, the bass is in no way warm. It's there, but it drowns out the mids and trebs. For me, not a good deal . . The isolation is sweet with a good seal as for all IEMs. I sleep with these in, so the comfort is good. 
 
The only downside is I have been through three pairs and am on my fourth. . . My first pair lasted about 6 months when the right ear went out. I sent in the warranty and got half off on my second pair. My second pair last a month . . then my third pair lasted the longest at about a year, and now my most recents ones are still going strong. I have heard other complaints about the right earbud going out, but to be honest I sleep and roll around with them in . .. so they would probably have lasted much longer had I taken better care of them. In any case, good IEMs, and worth the $20 or so bucks

For the price, you probably won't get a much better over the ear headphone. Any headphone worth buying over $200 needs an amp. There are Sony brands around the same price that are good as well, but I've found these deliver an overall better sound. At a REASONABLE volume, these have a sweet airiness to them; almost as if you're mid row at an outside concert. They deliver decent bass (although not as much as I like), some good mids (which personally I think are the best part of these), and a clear treble. Now, its not CRYSTAL clear- it does get sloppy at times, but mostly when listening at high volumes. I think what they tried to do with these is balance out the high, mids, and low as best they could, making these cans a jack (or an apprentice ) of all trades, but a master of none, if you will.  
 
On the comfort end, these are very comfortable. Now, if anyone has ever tried the Bose Quietcomfort, these are a couple notches down on the comfort rating. None the less, I've worn them for hours comfortably. 
 
For 115 dollars I was very pleased with my purchase, and I believe now that they are even cheaper (at B&H photo online). 
 
One side note though, is that for me, these phones needed burn-in time. About 20 hours worth I would say. The treble was very overpowering when I first got them, but after leaving them on all night, they sounded much better. (or perhaps I got used to the sound signature, or whatever you believe
