Sony MDR-EX51LP

The Sony MDR-EX51LP is a pair of silicon, in-the-ear, earbud-phones designed to fit snugly inside the ear. It utilizes a closed-type design for minimal outside noise, alongside super-small 9mm Neodymium drivers that generate a powerful bass response.

In fact, the MDR-EX51LP’s drivers use only 1mW of input power to achieve a 100dB sound pressure. Additional features of the Sony MDR-EX51LP earbud-phones include a stylish/neck-chain cord, a gold-plated mini-plug, and a compact case for storage. The Sony MDR-EX51LP retails for $29.99 and comes with a 90 day limited warranty.
