The Etymotic Research MK5 Isolator Earphones deliver clear sound and great details using high performance dynamic drivers. Just like their more expensive models, the MK5 offers Etymotic’s renowned passive isolation of 35-42 dB attenuation.
Accurate Earphone Reproduction
When tuning in-ear monitors to accurately reproduce a recording of a live performance, the goal is for the sound hitting the eardrums to be identical to that at the original performance. To achieve this, the acoustic properties of the ear must be factored in. The acoustic resonance and horn effects of the ear change a flat audio signal entering the open ear into sound with a (2700 Hz) high-frequency boost, which is the same response heard at the eardrum in a typical ear. That is the reason for the “hump” in the frequency response graph, which assures the eardrums perceive a perfectly flat frequency response for all frequencies.
