Marketed towards consumers as an alternative to their stock buds or basic headphones, the Sony MDR-KE30LW is a low priced dynamically driven open-backed earbud. At $24.99, the MDR-KE30LW is driven by a 13.5mm driver and includes a built in carabiner which makes cable issues a thing of the past. Sony's poor warranty may be an issue, but at only 25 dollars, such a loss may not be as hard to bear as the $299 MDR-EX700LP. Available in black, white, pink or blue.
