ER4S in ear monitors 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 because the response of the ER4S matches the response of most typical monitor loudspeakers. The high accuracy and exceptional sound isolation of the ER4S have made these in ear monitors popular with musicians, recording engineers and audiophiles. ER4S earphones can be used with a headphone amplifier when using low power portable devices. Included with every pair of ER4S in ear monitors is an industry-exclusive channel matching compliance graph signed by the Etymotic engineer who precision matched and custom tuned the balanced-armature drivers.
