ABOUT ET YMOTIC RESEARCH ABOUT ER-4 EARPHONES Noise reduction with ER-4 MicroPro earphones occurs naturally from the inserts. Other earphones with active noise-cancelling add circuit noise and require bulky batteries. In-the-ear, high fidelity transducers combine flat frequency response with isolation from external noise. The white 3-flange eartips provide 35 dB average external noise isolation. -

CD and MP3 recordings. The sensitivity is comparable to home and professional earphones. ER-4S earphones are ideal for home stereo use and computer use. ER-4S earphones can be used with a headphone amplifier when using low power portable devices. ER-4S is the earphone preferred by musicians and audiophiles. -

In addition to six white 3-flanged eartips, ER-4 MicroPro Earphones are supplied with ten disposable foam eartips. Both types provide excellent sound reproduction when properly inserted. White 3-flange eartips These reusable eartips should be cleaned regularly. Cleaning the white 3-flange eartips 1. -
Page 8: Insertion
Blue earphone = left ear Try the white 3-flange and foam eartips to determine the best fit for comfort and isolation. The sound quality and noise isolation depend on how well the eartips seal. If the earphones seem to lack bass, insert the earplug deeper into the ear canal to obtain a better seal, or try the other eartip option. -
Page 9: Changing Filters
CHANGING FILTERS ER-4 MicroPro Earphones have special filters that shape the frequency response and prevent earwax from entering the earphones. These filters, identified by a green acoustic mesh in a small metal barrel, are located at the end of the earphone and are visible when the eartip is removed. When the filters become clogged they should be replaced. -
Page 10: Proper Care
• Do not expose earphones to extreme temperatures. • Avoid dropping or strong impact. Extreme shock can damage the earphones. • Always leave an eartip on the earphone for shock protection. • Keep earphones away from water as this can adversely affect sound quality. Perspiration entering the nozzle may cause the earphone to temporarily stop working. -
