Custom earphones from Jerry Harvey Audio in collaboration with Astell&Kern

The siren series in-ear monitors are named after famous rock songs about women. Jerry Harvey Audio produced a special version of the Roxanne tuned for the Astell&Kern in 2014. The collaboration was so successful that the two companies will now release two more models, Layla and Angie.

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.

Red & Black Kevlar fibre shell with Carbon fibre logo insert.

The Layla is the first earpiece I've designed to be a reference/mastering IEM.

And this Angie is the little sister to Layla.

The dual low, dual mid and quad high configuration gives a very accurate representation of whatever source it has to reproduce. The audio signature is reference quality. The Angie has the same 4th order crossover network as Layla.

The Angie bass response is perfectly flat when attenuated or up to +10 dB of bass boost at 60Hz when boosted. The Angie also has the most sophisticated crossover network ever put into a IEM. The shape of all crossover filters are all 4th order. This crossover circuit combined with the Freqphase waveguide and new proprietary drivers deliver an audio quality that will truly put you at the mix position in the recording studio whether it's hearing exactly what the mixer/producer and band wanted you to hear, mixing your own tracks or performing live.

Angie In Ear Headphones

Posted by on 18th March 2015

I am by no means a specialist audiophile and have only recently decided on upgrading my sound equipment to items purchased from Sound Fidelity UK.
All of the items that I have purchased from Sound Fidelity have been received in good packaging, speedily delivered and are of high quality second to none for an amazing listening experience.
My Wife and I have dealt with Michael and Rowan when information was needed on buying the latest addition to my AK240, the Angie in ear headphones. They were very helpful in getting this posted to me as soon as it arrived in the UK.
Listening to my music through them brought tears to my eyes, sounding very close to my home sound system with warm and crisp sounds mixing and arriving at my eardrums just the way it should.
I have not even bothered to adjust on the base gain as it sounds so good as is.
Thank you Sound Fidelity for offering such good products and for all the help in choosing what I have now.

Kind Regards,
