The ER-4 MicroPro Earphones (Power) 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.
The ER-4P is the newest model in the ER-4 family of MicroPro earphones.
