Jerry Harvey - JH Audio Founder
Jerry Harvey Audio is proud to manufacture Rosie by using old school craftsmanship, while using the most cutting edge Technology.
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."
