The Next Best Thing to Live Music.

ER4S MicroPro Reference Stereo Earphones

Ear-bud Style headphone
41dB Sensitivity
Warranty: 1 Year

The ER4S MicroPro earphones are the next best thing to live music, with noise isolation far surpassing that of active noise-canceling earphones. The ER4Ss require no batteries and can be plugged into any audio source. Their external noise exclusion allows you to hear the full dynamic range of recordings without having to play them at unnaturally high and unsafe levels.

ER4S 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 ER4S matches the response of most typical monitor loudspeakers. The high accuracy and exceptional sound isolation of the ER4S have made these earphones popular with musicians, recording engineers and audiophiles. ER4S earphones can be used with a headphone amplifier when using low power portable devices.
