"Radius Atomic Bass 2 earphones deliver the highest level of sound quality, superior construction, unrivaled comfort and unparalleled style. If you have small ears, large ears or any size in between, these ultra-light aluminum eabuds are designed to fit comfortably and secure and are as functional as they are fashionable. Radius Atomic Bass earphones are a must have for individuals with an active lifestyle."
"The Atomic Bass earphones' understated design is further promoted by the supercompact size of the buds. Even users with smaller-than-average ears should have no problem achieving a relatively secure and comfortable fit. Radius includes three sizes of silicone ear tips, and I had no trouble getting a good fit with the smallest of these. I found the earphones to be comfortable after more than two hours of wear". - (CNET)
