They have a clear, clean sound accompanied by rich bass. They feature neodymium magnets, the strongest permanent magnets known, which aid in giving the listener a strong bass sound. iSkin's website boasts a wide range of frequency response, from 20Hz to 20kHz. Cindy tested their promise by letting her keen ears listen to an Internet test designed for testing multimedia loudspeakers. Check out that test at: http://www.eminent-tech.com/music/multimediatest.html.

While performing all the tests beautifully, she was pleased that the Cerulean earphones were able to produce the 30 Hz tone, something that the web page said most speakers (including her $120 multimedia speakers) are unable to play.

We compared them in sound tests with Apple iPod earphones, and a pair of Razer m100 Pro|Solutions Protone In-Ear Earphones, bought on Woot for $29.99 for a 2-Pack. Not surprisingly, they did outperform the sound quality of the iPod earbuds, which retail for $29.99. Unfortunately we were both unable to tell any difference between the less expensive Razer m100 earphones, and the Cerulean earphones. Both sounded equally great.

The biggest plus to these earphones are the silicone "ear-buds" (The Razer Company calls them ear plugs), which come in three sizes to fit most ears. When fitted correctly, they help block out outside noise. Most quality earphones now come standard with three sizes of silicone ear-bud/plug.

It is very difficult to tell the right earphone from the left; the only clue is a very, very small letter L or R on the inside of each bud. By contrast, the m100s have asymmetrical cable lengths, so it's easy to tell: Left is the short cable.

We have to give these earphones 2.5 Apples. While they do produce very rich and crisp sound, and do fit quite comfortably, the hefty $100 price tag seems a bit steep for earphones that are really no better than cheaper ones. Another downfall of these earphones is that they seem quite heavy. Moe found that they seem to fall out of your ears easily, no matter which size bud you use.
