JH Audio Jessie Universal Dynamic Driver In-Ear Monitoring Earphones (Black)

Jerry Harvey Audio's Jessie™ is a universal–fit in–ear monitor built around a single 12mm dynamic driver, engineered to deliver professional monitoring quality without the custom–moulding cost or lead time. This wired IEM targets working musicians, worship teams, bedroom producers, and entry–level performers who need reliable sound reproduction across rehearsals, small gigs, and home sessions. The driver's natural, full–range response makes it genuinely usable straight out of the box.

The 12mm dynamic driver spans 20Hz to 40kHz, giving you extended bass clarity and crisp high–frequency detail across the monitoring spectrum. Sensitivity sits at 112dB with 32Ω impedance, making the Jessie efficient enough to run from any standard audio interface or mixer output. The package includes a 3.5mm wired cable and four ear tip sizes (S, M, L, XL), allowing you to dial in fit and acoustic isolation without trial–and–error buying. Weight and form factor prioritise all–day comfort for stage use or long studio monitoring sessions.

The Jessie suits anyone stepping beyond consumer earbuds into serious monitoring. Churches and touring bands rely on this driver's durability and consistent sound; home recordists appreciate the plug–and–go simplicity; gigging musicians value the combination of price, reliability, and actual sonic performance. It's not a boutique signature sound—it's engineered neutral enough to work across vocal–focused, instrument–heavy, and mixed–content monitoring scenarios.
