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. This allows listeners to hear the full dynamic range of recorded or live music at safe levels.

Additional "customization" can be requested by ordering a set of custom-fit ER-4 Chameleon Ears. These earmolds come in a variety of colors and give even further comfort and isolation performance to these monitors.

(Note: This product is produced for the enjoyment of listening to audio/communication devices. But please remain aware of the dangers of listening to these devices at a loud volume level (85dB+). OSHA regulations state a volume of 80-85dB is safe for an eight hour period of time. If you are concerned about your hearing, please consult a hearing specialist who can advise you about your safety levels with your audio device.)
