A collaboration between Jerry Harvey Audio and Astell&Kern, the Rosie is the fourth in the acclaimed Universal fit Siren Series of in-ear monitors. The alliance of JH Audio and Astell&Kern is seen as one of the most meritorious ones in the history of audio.
The last model in the Siren Series, this IEM is named after the iconic AC/DC Song “Whole Lotta ROSIE”. Then legendary lead singer Bon Scott was inspired to write this song after having a one night stand with a “rather large” Tasmanian woman. Rosie is still in ACDC set today and a favorite of the Band's fans worldwide.
These earphones have 8 c ustom-made proprietary balanced armature drivers in each earpiece. You can achieve variable bass output through adjustments from the cable, we believe, a great feature for an IEM.
The larger-than-average ear shells accommodate the tubing that ensures all frequencies arrive at the ear at precisely the right time, without letting the vocal definition suffer. JH Audio's Freqphase technologies grace the rest of the Full Metal Jacket piece.
An additional balanced cable specifically for Astell&Kern players will allow you to experience the full potential of music and seamlessly integrate with your player.
The absolutely impressive luxurious feel and its high-end goodness, paired with great sound delivery, will never let you want to let go of the Rosie.
