Summary: I have had two pairs of Etymotic ER6i earbuds that died after 18 months of daily use, i.e., out of warranty. They were excellent and had a transparency that I loved, but they were expensive. I tried these and am very pleased. Soundwise they are good. Good tight bass and ok high end, that I must compensate for with eq. BUT overall they are better than many Sony's, Ear Candy and Bose, though not as good as the ER6i.
Summary: Unlike most of the reviewers here, I'm lukewarm on these earbuds. When I ordered these earbuds, I didn't understand that they have a peculiar shape that, if it doesn't require you to use a special procedure to put them on, at least encourages you to do so. The procedure is to loop the wire over your ear before inserting the earbud into the canal of your ear. The wire feels annoying at first, though that annoyance goes away after a few minutes.
Summary: These headphones are great, until they break. After a few months, the insulation on the individual ear wires started breaking in places from being bent back and forth, exposing the wires underneath it. I covered it in parts with electrical tape. The headphone jack has slipped from the rubber tubing around it, making me have to glue it back into place. If I was less patient, they would have gone in the trash.
Summary: I'm hard on earphones. I've destroyed Shure E2C's and 110's not to mention many other brands. I was looking for a cheaper product with similar performance. My top criteria are: sound blocking, durability, sound quality, comfort, and value. If you use the orange Shure foamies you won't be able to beat these earbuds (It's a tight fit but it works). You also can't beat the price.
Summary: I bought 2 sets of these earbud headphones for my boys to use with their I-Pods because the headphones that came with their I-Pods hurt their ears. The earbuds are very light weight, have a unique angle of insertion and sound wonderful ( much better bass response than I expected), but the biggest advantage is the comfort of the earbuds in the ear canal! If you have small ear canals or children then these earbuds are inexpensive and certainly worth a try!
Summary: I purchased these because I had a VERY long flight to New Zealand and my iPod headphones just didn't do it for me on the airplanes. The loud engine noise creates a steady hum that you eventually acclimate too and you just raise the volume. When you get off the plane, you realize that your iPod is at an unsafe level for your ears! I especially had difficulty listening to classical music, where the change between quiet and loud can be sudden or grow overtime.
