ER•4B (Binaural) MicroPro earphones
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. It was developed from the ER-1 earphone that is referenced to a flat diffuse field and used primarily for speech reception research, where the goal is to produce the same frequency response at the eardrum as would be produced in the live situation.
<b>Next Best Thing to Live Music</b>
- ER•4 system includesTransparent, reference-quality sound.
- For audiophiles, performing musicians and recording engineers.
- For mixing, monitoring and critical listening.
- Accurate real-ear response.
- Unsurpassed isolation from outside sound.
The ER•4 MicroPro™ earphones are the next best thing to live music, with noise isolation far surpassing that of active noise-canceling earphones. The ER•4s require NO batteries, and can be plugged into any audio source. Their external noise exclusion -- 35 dB with 3-flange eartips, 42 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. The earphones come in three styles: ER•4B, ER•4S, ER•4P.
