Yamaha has just unveiled three high-quality in-ear headphones – EPH-20, EPH-30 and EPH-50 – each with three ear buds, a different driver unit, and allowing the customer to choose from a range of sizes and colors according to his or her preferences.
Yamaha EPH-20 comes in black, reddish-brown, indigo blue, lime green, and hot pink colors with a 10.7mm driver unit.
EPH-30’s driver unit is 9mm, the choice of colors is limited to the classic black or white; this set features a function that drowns external noises.
Advertized as a professional-quality set, EPH-50 is equipped with a 13.6mm sound driver and a 1/4-inch plug adapter for home stereo use.
All the three new Yamahas have durable construction (EPH-50 made extra durable) and boast of high efficiency that goes easy on mp3 batteries. They use dynamic type sound rivers on 20~21,000Hz frequency response.
