Astell & Kern AK Rosie - earphones : 

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 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 6 driver ROSIE is reminiscent of the legendary JH 13. Rosie has the extention and silky defined Mids of the JH 13 with the adjustable Bottom and weight of the Roxanne. Rosie is a game changer in IEMs below $1000.00.

- 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.
- 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.

User controlled low frequency drivers with the adjustable bass (0 - +15dB). Frequency ranges from flat bass response up to +15dB (10Hz to 100Hz). 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. AK380/AK320/AK240/AK120Ⅱ/AK100Ⅱ provides a balance output with its specific 2.5mm 4pole terminal. Rosie is originally designed and tuned for the AK380 balance output and provides a balanced cable specially made to connect to the AK380. This originally designed 3.5mm and 2.5mm cables are specially made by Moon Audio in USA and both are included in the package. Jerry Harvey Audio is proud to manufacture Rosie by using old school craftsmanship, while using the most cutting edge Technology.
