Etymotic ER-4 MicroPro™ Earphones DISCONTINUED

The ER-4 require NO batteries, and can be plugged into any audio source. Their external noise exclusion (33 dB with 3-flange eartips, 41 dB with foam eartips) allows you to hear the full dynamic range of recordings without having to play them at unnaturally high and unsafe levels.

Specifications:
Frequency response: 20 Hz to 16 kHz ±4 dB
Acoustic polarity: + electrical = + acoustic
Transducer type: dynamic 1 kHz sensitivity (ER-4B/ER-4S): 108 dB SPL for a 1.0 volt input
Impedance (ER-4B/ER-4S): 100 Ohms nominal
Maximum output: 122 dB SPL
Maximum continuous input (ER-4B/ER-4S): 3.0 Vrms
Weight: less than 30 grams.

ER-4B (Binaural) earphones are for the binaural recording enthusiast. The ER-4B is an ideal earphone for use with material that has not been equalized for loudspeaker playback.

ER-4S (Stereo) earphones were designed to compensate for the high frequency emphasis in all CD recordings, in order to provide accurate sound reproduction. ER-4S earphones can be used with a headphone amplifier when using low power portable devices. The response of the ER-4S matches the response of most typical monitor loudspeakers.
