Product Description

ER?4S (Stereo) earphones were designed to compensate for the high frequency emphasis in all CD recordings, in order to provide accurate sound reproduction. Performing musicians often use them as in-ear monitors because the response of the ER?4S matches the response of most typical monitor loudspeakers. The high accuracy and exceptional sound isolation of the ER?4S have made these earphones popular with musicians, recording engineers and audiophiles. ER?4S earphones can be used with a headphone amplifier when using low power portable devices. Box Includes: ER?4 MicroPro earphones 5 ft. cord with 3.5 mm stereo phone plug 1/4" stereo phone adapter plug Six 3-flange eartips 10 foam eartips Filter changing tool 4 replacement filters Shirt clip Pouch Storage box
