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.
