Yamaha has just launched its first line of in-ear headphones which comprises three models' the EPH-20, EPH-30 and EPH-50.

As indicative by the naming, the EPH-50 is the flagship pseudo-audiophile variant with 13.6mm drivers, sturdier construction and includes a quarter-inch adapter for home stereos. These come in black or white.

The EPH-30 is the more mainstream positioned model with 9mm drivers and a more conventional design, whilst the EPH-20 sits at the entry-level with slightly larger drivers (10.7mm), aimed at buyers who don't want to spend a premium whilst still getting satisfactory quality. These come in five colors of your choice.

The new EPH series is designed to work fine with iPhones, iPods and all other devices with 3.5mm jacks. Pricing starts at $30 for the EPH-20s, whilst the EPH-30s and EPH-50s come in at $50 and $100 respectively.
