x 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 fourth offering in the Siren Series is aptly named after the iconic ACDC Song “Whole Lotta
ROSIE”. Then legendary Lead Singer Bon Scott was inspired to pen this song after having a one night
stand with a “rather large” Tasmanian women. Rosie is still in ACDC set today and a fan favorite.

The 1st reference/mastering IEM from Jerry Harvey Audio
Full Metal Jacket
Each Body, Cap and Sound bore are machined from one Solid Block of Aluminum with Carbon Fiber Logo Plate insert.
All new proprietary Driver designs
This series of IEM’s were designed to be used as a Mastering reference tool because the high driver was designed for optimum top end extention with minimal distortion. The mid driver is perfectly flat from 10Hz to 5kHz. Low driver designed for steeper low pass and with virtualy no distortion.
SoundrIVe Technology
(Quad Driver Technology)
Rosie was equipped with soundrIVe Technology, using Jerry Harvey Audio's proprietary quad drivers. 8 drivers [Dual Low, Dual Mid, Quad High] configuration that offers the widest frequency range you’ll ever hear.
FreqPhase Technology / Stainless Steel Tube Waveguide
FreqPhase corrects Time and Phase of multiple Drivers. The Waveguide ensures each driver signal arrives within 0.01 milliseconds, resulting in a Phase coherent IEM.
4-pin cable connection with Machined Aluminum Collar mechanism provides a more secure and strong connection with earpiece and will also help to protect it from sweat and dust.
Variable bass output, adjustable from cable
User controlled low frequency drivers with the adjustable bass (0 - +15dB). Frequency ranges from flat bass response up to +15dB (10Hz to 100Hz)
