ER-6 Isolator Earphones, in-the-ear, high-fidelity transducers, were developed to combine flat frequency response with isolation from external noise. When properly sealed, these earphones provide 15-20 dB of external noise exclusion. This allows the listener to hear the full dynamic range of recordings at lower reproduction levels.

Provided with a soft silicone flanged-tip for a good seal with comfort, they are ideal for travel and commuting, as well as for professionals looking for smooth, extended high-frequency response with great sounding bass qualities.
