ER•4 MicroPro earphones were the first noise-isolating high-fidelity in-ear

earphones to use ACCU•Driver™high performance, balanced armature drivers.

These high-definition transducers combine flat frequency response with

passive noise isolation. Noise reduction with ER•4 earphones occurs naturally

when the eartips are sealed in the ear canals.

Included with the earphones is the Channel-matching Compliance Graph

showing frequency response curves of each custom-tuned,balanced

armature driver.

An assortment of ACCU•Fit™eartips is provided in this package. The triple-

flange eartips reduce sound an average of 35 dB,which is approximately

98% noisereduction. The foameartips provide slightly more (42 dB) sound

reduction. Lowering outside sound allows you to hear the fulldynamic range

of the recording without having to play it at unsafe levels.

The ER•4 MicroPro series earphones produce the highest sound quality of any

high-definition earphones on the market today. We hope you enjoy them.
