Consult a physician oraudiologist if you have excessiveear wax,difficulty

inserting the eartips, or discomfort after prolonged use.

ER 4 MicroPro• earphones exclude most external sounds even at lowlistening

volumes. It is unsafe to use insert earphones while driving a motorized

vehicle, operating machinery, bicycling or

jogging,because you may not be alerted

to potential danger.

Do not use the earphones at excessively loud levels. Noise-induced

hearing loss is a function of exposure time,the average soundlevel and the

peak of very loud sounds. Decreased listening levels allow for longer periods

of safe listening time.

ER 4 MicroPro• earphones were the first high-fidelity,in-ear earphones to

use balanced armater drivers.These high definition transducers combine

flat frequency response with passive noise isolation. Noise reduction with

ER 4 MicroPro• earphones occurs naturally whenthe eartips are sealed in

the ear canals. Earphones with active noise-canceling add circuit noise and

require batteries.

The triple-flange eartips provide 35 dB average soundreduction,which is

approximately 98% noise isolation. Foam eartips provide slightly more

(42 dB) average external noise isolation. Lowering surrounding noise allows

the listener to hear the full dynamic range of recordings at lower

reproduction levels.
