Marketed towards consumers and audiophiles alike, the Sony MDR-EX90LP is a medium priced dynamically driven canalphone. At $99.99, the MDR-EX90LP is driven by a 13.5mm driver. While not as large as the Sony flagship, the MDR-EX700LP, this driver is still large enough to provide ample bass where single armature based models may struggle. Providing isolation for use on-the-go, the MDR-EX90LP is a great choice for those interested in preserving their hearing while enjoying great sound. Sony's poor warranty may be an issue, but at only 100 dollars, such a loss may not be as hard to bear as the $299 MDR-EX700LP.
