The black HPH-50B Compact Stereo Headphones from Yamaha are entry-level headphones that deliver professional-grade sound with a carefully-balanced bass and treble while playing back recorded media or performing on a digital instrument. These headphones feature a swivel mechanism that allows the driver unit to turn up to 90° to fit the angle of your ears comfortably, and a length-adjustable headband. The 6.6' cable terminates in an 1/8" stereo plug; a 1/4" adapter is included to allow you to plug these headphones into various instruments.
