The large 13.6mm dynamic driver borrowing technology from some flagship products, the jh3 features a bass dynamic driver that is the same size as that of a flagship dynamic driver iem. The newly designed magnetic structure allows the magnetic flux to increase by a significant 20% ndash resulting in lush, full mids, and potently dynamic bass. The jh3s meticulously designed internal structure features 2 exclusively customized ba drivers. These ba drivers are placed closer to the opening of the sound tube for less treble loss. Overall, thanks to its design, not only do the jh3s 2 ba drivers sound transparent, but they also work perfectly with the bass dynamic driver for a cohesive sound, without disjointed treble and mids. The aluminium alloy construction is shaped with a 5 axis cnc machine, then carefully hand polished and put through many other manufacturing processes used on high end products. Each ldquostriperdquo of light and shadow is clearly showcased. Finally, pvd coating is also applied to the surface of the jh3 for better rigidity of the iems, allowing that mirror like finish and stripes to further shine and last longer against wear and tear. The patented balanced pressure relief system has numerous benefits. For sound quality, balancing air pressure inside and outside of the jh3 reduces distortion and allows for clearer bass due to letting the driver move as necessary. For comfort, the balanced pressure relief system eliminates pressure on your eardrum, allowing you to listen longer without discomfort. Every last detail of the jh3 has been thoughtfully considered. The usage of the 0.78mm 2 pin connectors ensures compatibility with a wide variety of cables, including those that enable convenient wireless bluetooth connections such as the utws series. The included monocrystalline copper cable contains 4 strands with a total of 120 wires, with each independently isolated to prevent interference. L shaped connectors are used on the ear unit side to better fit the curvature of the human ear for better comfort and ultimately more enjoyment of your music. The jh3 headset has been certified by jas and cea, its ability to bring you accurate, high fidelity audio as the artist intended. You can enjoy a clear, hifi sound from these earphones.
