| ER-4 MicroPro Series
 ER-4 MicroPro Earphones are high fidelity transducers developed
specifically to combine flat frequency response with isolation from
external noise. They deliver transparent, reference-quality sound and
provide at least 20-25dB of external noise exclusion at all frequencies,
which allows listeners to hear the full dynamic range of recorded or
live music at safe levels.
