The Hook-X is the first attempt at a hybrid in-ear monitor design utilizing the planar magnetic driver in combination with a piezoelectric (PZT) driver. These two driver types are among the most sensational driver technologies in the audio industry, and have never been utilized together in an IEM format. We took on this momentous concept, and through careful engineering and testing, have successfully created an IEM that encompasses the powerful characteristics of these drivers fashioned with tonal perfection. Unlike other IEM novelties that simply cram in hyped drivers, we our proud to achieve a product that is tuned to balance and allows the listener to both appreciate the acoustic superiority of these drivers as well as enjoy the music through their harmonious tonality.

The planar magnetic driver utilizes a thin ribbon suspended between two powerful magnets through which electrical currents run. The advantage of a planar magnetic driver is the extreme responsiveness compared to dynamic or balanced armature drivers due to its lower mass and strong magnetic field. We manufactured our own large 14.2mm planar driver, which is driven by powerful N52 magnets. The precision of this driver allows incredibly punchy and impactful sub-bass response, as the ribbon is more responsive to transient signals. Furthermore, the full frequency range is effectively extended from 20Hz to 40kHz to produce an upper treble response previously unobtainable in an IEM. Internal housing structure design and acoustic damping system were carefully brought about to achieve a balanced target tuning, a rarity among IEMs that utilize the planar magnetic driver.

The piezoelectric driver achieves enhanced treble response through vibration of piezo elements within the housing. In cooperation with an external team with military engineering backgrounds, we have designed a double-sided layering system consisting of 18 ceramic piezo elements that has been fine-tuned after more than 100 acoustic shock simulation experiments. Each of our PZT drivers undergoes 52 complicated processes during production, and is hand tested and paired. In addition to the planar magnetic driver’s extended treble response, our PZT driver adds an extra dimension of sonic resolution and air that is incomparable with typical balanced armature or even electrostatic drivers.

Open-Back Design
For both tuning and acoustic properties, the Hook-X adopts an open-back design. This allows the maximum amount of airflow to highlight the planar magnetic driver’s characteristics. Additionally, this opportunity opens up the soundstage compared to typical IEMs, mimicking the openness and realistic playback of open-back planar headphones. Finally, the open-back design prevents the buildup of pressure within the ear to reduce hearing fatigue. The housing of the Hook-X was software designed after a large number of simulation experiments to match the typical ear angle and wearing experience. Each unit is crafted from a high-precision 5-axis CNC to ensure uniformity of the acoustic chambers. From the housing design to the driver assembly, each aspect of the Hook-X is a demonstration of workmanship, engineering prowess, and acoustic tastefulness.

Interchangeable Connector Cable
The Hook-X comes standard with a modular connector cable terminated to 0.78mm 2-pin jacks. This means that you can simply swap out the connector between the 4.4mm and 2.5mm balanced and 3.5mm unbalanced jacks to use with any of your devices. This incredible design limits the need for bulky adaptors. The cable itself is made using OCC silver-plated coaxial shielded wires that enhance the transparency of the hybrid drivers.
