Radius Atomic Bass Earphones for iPhone

The Radius Atomic Bass for iPhone (RK-CA511K) is a pair of entry-level in-ear earphones with iPhone connectivity released in late 2008. These earphones are Japanese designed, and sold through a Tennessee-based company.

Radius claims these ear-buds offer expansive low-end response, meaning ample bass for the listener’s music. These earphones come in several different colors: black, red, silver and pink. The cable is white except for the black version, which has a matching cord. The cable reaches 48” in total, and is designed to fall down the front of the user with its even lengths. This style is suitable for most levels of activity, including sports. The integrated mic is small and compact, with the call/answer button about halfway down the left side Radius includes three sizes of silicone ear tips, which should give users a choice when it comes to finding a comfortable fit.
