Description

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.

The ER-4P (Portable) earphones can be used with portable CD, MP3, DVD and other players without requiring an additional amplifier. As compared to the ER-4S, the ER-4P has 10 dB greater output at high frequencies and 13 dB greater output at low frequencies. The higher sensitivity and enhanced bass of the ER-4P have made it the most popular earphone for most uses.
