Jerry Harvey JH Audio founder

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."

– Jerry Harvey

Not What I First ThoughtReview by David D.

I bought this IEM on Drew's recommendation to pair with my Calyx M. I was very disappointed when I first tried it, and doubly so because I knew I couldn't return it. It was muddy, bloated - pretty horrible though.
But I remembered reading that it came with the bass fully maximized. What the hell, I'll turn it down a bit. I set it to the 12 O'clock position and suddenly the treble started to shine and ring like crystal, the midbass appeared and the bass firmed up wonderfully. It's a different animal with the tamed bass. (Posted on 2/16/2017)

These A&K JHA Rosie IEMs are simply fantastic at this price point.

The construction is best in class with the machined housings, adjustable bass, and quality connectors and cables. Of course, the most important thing is how do they sound?!

The sound is detailed and accurate across the full spectrum. Individual instruments are easily revealed with the combined sound being very musical. I personally find a touch of base boost works for my taste but they clearly can put our more if that's your thing.

The increased base comes in solid, natural, and not bloated. Midrange and highs are balanced and just right for the varied musical styles I listen to (Rock, Jazz, Acoustic). I should also note that I did go with the Black Dragon cable upgrade which adds a touch more clarity/detail over the stock cables which were certainly acceptable.

These IEMs really perform when driving with my MOJO running Tidal HiFi downloads on my iPhone. Makes a great mobile system. (Posted on 4/5/2016)
