Love these things 
2008-07-04
BIG sound for a little price. The various sized rubber "gaskets" assure they will stay in place and can affect the level of bass that you desire. I also like the fact that one earbud cord is way longer than the other so you can wrap it behind your neck. I highly recommend them.
EP 630 vs. MDR-EX51LP 
2008-07-01
I've owned the Sony MDR-EX51LP's for a year or two, and honestly they've served me well. The L-plug is a great feature which I find protects my iPod earphone jack from loosening or breaking because it lies closer to the iPod body (less leverage, get it?). If you're not careful, the silicon sleeves can fall off when you put the earphones in/out of your pockets, and that's why the blue/green case is a great extra. I actually lost one of my silicon sleeves and replaced it with Shure sleeves from Amazon for 10 bucks. (http://www.amazon.com/Shure-EA506A-Replacement-QuietSpot-Headsets/dp/B000F6570C/ref=pd_bbs_5?ie=UTF8&s=electronics&qid=1214903819&sr=8-5) They actually made the earbuds more comfortable and sound slightly better, so I'd strongly recommend them.
Recently I acquired a pair of EP 630's by Creative. Overall, both are very comparable and evenly matched, but each has its strengths and weaknesses.
For sound quality, the EP 630's easily beat the MDR's, even with the Shure sleeves. Sound is crisper and clearer with the EP 630's, and a little more flat with the MDR's. As for comfort, both are very similar. While the Creative's are lighter and smaller in your ear, the Sony's (with Shure sleeves) have a fuller fit that just feels right. Without the Shure sleeves, the MDR's are slightly lacking. The cord length for the 630's is much shorter which I find to be a nuisance, but the MDR's are perfect, maybe even slightly long. With the MDR's, the right wire is longer than the left wire. I believe this is referred to as a J design, but I'm not sure. Its convenient because usually you put the longer wire behing your neck. This way, if you want to hear from only one ear, the longer wire will rest on your shoulder. The Creative's have a standard Y-shaped cord, so if you let one earbud dangle, it tugs at the one in your ear. The material surrounding the MDR's is softer and spongier, which feels high quality at first and doesn't tangle too much, but after prolonged use they will wear down. I've had to use electrical tape to fix some exposed wire underneath, but now it works like a charm. The 630's cord feels much more durable, but as they haven't been used nearly as much as the MDR's, I'm not definite. Another advantage to the MDR's is the cord does not transmit external sound like the 630's. I'm able to hear every touch with the 630's, but with the MDR's sounds are muffled or not noticeable (Big plus if you use these on the go). Lastly, and probably least, is the L-plug for the MDR's which I think is great, but not a huge deal and probably shouldn't sway your decision much.
In summary,
Sound - Creative EP 630's (easily noticeable advantage)
Comfort - Creative EP 630's (barely beat the MDR's with the included sleeves. With Shure sleeves, they're equal)
Cord length/design - Sony MDR-EX51LP (No brainer, the Creative's annoy me because of this. The J-shape is much more convenient than the Y-shape as well, but that's personal preference)
Cord material - Sony MDR-EX51LP (Another no brainer. I use these on the go and the constant clatter from the 630's is unbearable)
Cost - Sony MDR-EX51LP (almost 10 bucks, up to you if its worth it)
From the way I weigh each of the advantages and disadvantages, the Sony's beat the Creative's. However, you might think different, decide for yourself. I find myself using the Sony's often and the Creative's not at all because I'm usually on the move with my music and the Sony's are much more portable friendly as already mentioned. So my conclusion is this: If you'll be on the move, take the MDR's, because they have a clear advantage there. But if you're not, take the EP 630's, because for the price, you can't beat the sound quality. Just my 2 cents.
Good for the money 2008-06-27
Nice bang for the buck. The pods do stay in your ears well and do not need to be adjusted. I purchased them for the purpose of using them at the gym or running. Sound quality is decent but if you are looking for exceptional soumd these are not the pods for you.
Not so great 
2008-06-15
These are OK for the money (great Amazon price compared to BestBuy/Target), but like the JVC $9.99 earbuds or Bose $139 much better.
PROs: good outside noise exclusion
CONs: hardly any bass, didn't fit well in my ear
Some people really like these, but didn't work well for me.
Buying my 3rd set 2008-06-15
I have used these daily for about 4 years and have yet to find anything better. They effectively block outside noise, have great sound, and are very comfortable to wear. I keep a pair by my computer for playing games, and another to use with my mp3 player. After 4 years, one of the sets is getting a little frayed as expected. After reviewing all the other comparable products on Amazon, I'm buying another set of these.
good, but not so 
2008-07-20
Facts
-The cord is really long
-It will fit your ears very good
-Sounds nice
i just have 3 days with it, i have a sansa e260, and the sound its almost equal to the earphones that comes along with the player, i dont recomend this product if you already have an earphones or earbuds cuz probably (if the quality is a lil' decent) the sound wont be much better and the price is too high, i dont recomend this product at least u want something with just a decent quality at a expensive price.
Great sound, mediocre cord 2008-07-13
I would somewhat agree with another reviewer that while the sound quality and overall range is great the cord didn't hold up well. I guess I did get my $20. worth.
Great Value, Great Product 2008-07-12
These headphones are some of the best I have ever purchased. They have great sound quality and really block out other noises. I have purchased two of these, one about 1.5 years ago and another just a few weeks ago when the first ones broke. 30 bucks for these comfortable headphones is a great deal. I would recomend buying these headphones if you want to block out noise, have great sound quality and want a great value.
Differences Between MDR-EX51LP and MDR-EX71SLA 2008-07-07
Although this set of headphones was a few dollars cheaper, I should've gone with the MDR-EX71SLA. I cannot tell the difference so I will have to say they've equally got great sound quality. I'm with most of the reviewers, I do not like nor do I get why Sony created the odd length of the cord, however the MDR-EX71SLA allows you to go super short or super long. I preferred the super short so I could clip my shuffle on my collar while working or jogging. Also, the MDR-EX71SLA has rubbery head phones while the MDR-EX51LP have hard plastic head phones. I found it easier to get the ear buds snug in my ears with the rubbery head phones than the plastic ones. I never experienced the cord malfunctions as some of the reviewers have, the only reason I had to get a new pair was because I accidentally left the long cord outside while I was driving on the freeway for about 15 minutes. I thought something was wrong with my car, I was dismayed when I found out I mangled my headphones. The headphones were pretty banged up but still worked for a good year after that at least through one headphone.
Not worth the money 2008-07-05
I bought these earphones as an addition to the Koss earphones I already own. The sound is OK, but not as good as I expected and the "holder" is a joke. Would not buy them again at any price. The Koss earphones are better quality, better sound and a real pouch to hold them for less money.
