Summary: Pros: -Great isolation (3 different fitment sizes) -Warm bass -Overall decent sound (see other reviews, they pretty much sum up what I think about the sound). Cons: -CABLE NOISE (!!!) -somewhat sharp 5-8khz region Comments: For the price, I think these phones are great. The sound quality is pretty impressive, and easily driven (though with the nice isolation, you really don't need to have your phones up very loud).
Summary: Ratings are based on the current price and compared to other IEM. These can be had for as low as 20 dollars. The main problem I have with these IEM is the tinny highs. I just can't get used to that. I have very piculiar ears, and these are the first IEM that more or less stay in place.
Summary: These are the headphones I use for work and commuting. They're great value, the scores are low only because we're comparing with $2000+ headphones. These are better than the EX71s sound wise, but are very slightly less comfortable. I wish they had uneven cord lengths, I think some versions do but mine are equal. Highly recommended.
Summary: There popular earbuds are both inexpensive and offer a pleasing upgrade to iPod-style buds. Solid design and extreme portability make them even more appealing. - The EP 630 has a warm, fairly detailed sound, thanks to the soft rubber earpieces, which also offer good isolation. Unfortunately, the cables are also microphonic with any movement. Fair balance, though there's a small bump in the mid-range. - Durability is uncertain at this point.
Summary: For the $5 they are worth it. But not high quality. Highs and lows are compromised. ...............................................................................................................................
Summary: These earphones are pretty good for the price that I paid. You got noise isolation that really works if you are listening to music as well. If you are not listening to music, you only get some ambient sounds "muffled". It's still a good deal though, you do not need to buy those high-tech noise canceling headphones, just go with this one. Update: After 2.5 years of use, left earbud decided to stop sounding. Not exactly the best quality earbuds in the world.
Pros: Noise isolation works when listening to music, Cheap (when PM'ed)
Summary: You can't expect much when you only pay around $7 for this headphone. But it is actually a good buy for the price. It is very loud and it will do the trick if you are on a cycling, jogging, exercizing because you just need loud sound without the intention of getting good sound quality. If you are in a quiet place just listening to music you probably need better headphones because the bass on the EP-630 is not that great.
