Meet ROSIE™ – the rockstar earphone that defies expectations. Taking the best of the Ruby™ sound and cranking it up with a smooth, refined tuning, Rosie delivers a punchy, high-impact performance that’s all about efficiency. With fewer drivers, thanks to Pearl’s sleek design, she still manages to pack a serious sonic punch, delivering crystal-clear highs, tight bass, and vocals that cut through with attitude. Small in size, but mighty in sound, Rosie brings all the power you need without the heavy price tag. Our smallest universal yet, Rosie is perfect for those who want big performance without the big cost. Rosie is all about doing more with less. It’s rock and roll in its purest form: raw, real, and ready to roll.

The JH Audio™ Pearl™ Tri Amp Micro Speaker Management System is our latest innovation in audio technology. The system includes our Pearl Control Software and Pearl Loader program, which offer functions that allow users to precisely control gain, phase, time, and equalization of low, mid, and high frequencies of an in-ear monitor.

When used together, the Pearl and ROSIE will make it possible to reproduce any frequency response or audio signature.

Now available for Windows and macOS, the Pearl system ensures that users on either platform can achieve the ultimate, personalized, high-quality audio.

Our Pearl Control Software, which allows the user to shape the audio and program the Pearl with user-defined, instantaneous presets, will be included with the system. Multiple frequency response preset files will be included in the software, and we will publish new preset files as they’re developed. Using this software, users can set different levels for each ear, which is especially beneficial to those experiencing hearing loss. Additionally, the Pearl Loader function is used to instantly change the Pearl Processor from one frequency response setting to another via a USB-C cable.
