Angie by Jerry Harvey Audio
Jerry Harvey Audio custom earphones world's leading creator
and collaboration Astell&Kern
The Siren Series Universal fit IEMs plus Astell&Kern Playback allows you to hear the music how the Recording Artist and Mix Engineer intended.

The third offering in the Siren Series is aptly named after the Rolling Stones song Angie. Written by Mick Jagger and Keith Richards and recorded in November and December 1972, Angie is an acoustic-guitar-driven ballad, which tells of the end of a romance. Richards, who wrote almost all the music and lyrics for the song, claimed in his autobiography that the name Angie was a pseudonym for heroin, and that the song was about his attempt to quit using it while detoxing in Switzerland.

The audio signature is reference quality with the same 4th order crossover network as Layla. Angie's dual low, dual mid and quad high configuration gives a very accurate representation of whatever source it has to reproduce. Designed for optimum top-end extension with minimal distortion. The mid driver is perfectly flat from 10Hz to 5kHz. Low driver designed for steeper low pass and with virtually no distortion. Bass response is perfectly flat when attenuated or up to +10 dB of bass boost at 60Hz when boosted.
