Features Of JH Audio ROXANNE AION
In 2013, JH Audio revolutionized the IEM industry with the release of Roxanne, a custom stage monitor reference IEM named after a classic Police song. 4/Mid4/High4) on each side, and incorporated the first cable at the time to use a JH4pin connector. The JH4pin connector and cable incorporating the Variable Bass function became the symbol of JH Audio IEMs.
AION is the latest in a series that represents JH Audio's past, present, and future accomplishments.
The "Roxanne AION," the second product following the "Layla AION," retains the sound signature of the original Roxanne custom IEMs and uses the latest 7-pin connector. Combining the latest patent-pending technology and design with an ever-evolving, industry-leading manufacturing process, the Roxanne AION is a state-of-the-art IEM with the best sound possible. The shell of the Roxanne AION is made in Orlando, Florida by the same talented engineers and technicians who build JH Audio's line of custom IEMs that support thousands of professional ears on stages around the world. The shell portion of the Roxanne AION is made from carbon fiber blocks, which are formed by injecting and compressing resin into hundreds of layers of carbon fiber fabric. After an initial machining process, followed by a secondary hand-forming process, the Roxanne AION is precisely tuned and hand-assembled using state-of-the-art equipment. The striking faceplate design with black and white pearloid and oversized chrome logo makes the Roxanne AION one of the most visually appealing JH Audio universal fit IEMs to date.
The Roxanne AION uses JH Audio's patented "soundrIVe technology," a unique mini-quad driver configuration (four BA drivers). ×The Roxanne AION has a triple quad driver configuration with 12 drivers (4 high, 4 mid, and 4 low) in one housing to provide a vast, wide-range sound.
- freqphase™ Technology
JH Audio's proprietary phase control technology, "freqphase" technology, is used. This is JH Audio's patented technology that precisely controls the time axis and phase of each band in a multiple driver configuration. It achieves precise phase and time alignment at all frequencies, ensuring that each driver's signal arrives within 0.01 milliseconds, enabling the most accurate music reproduction as an IEM.
- Sonic Tube Chassis™ Technology
Sonic Tube Chassis technology is used. The internal chamber room is 3D printed and the 12 drivers are optimally positioned to reduce the internal volume of the shell body. freqphase technology allows for a compact shell design without sacrificing sound quality.
- Carbon Fiber Shell
Hundreds of layers of compressed carbon fiber textile are infused with resin and molded in an ergonomic design made possible by JH Audio's years of experience and expertise in custom IEM production. It provides a fit, stability, and sound insulation that fleshes out the custom IEMs. In addition, the striking faceplate design with white and black pearloid and oversized chrome logo makes the Roxanne AION one of the most visually appealing JH Audio universal fit IEMs to date.
- Acoustic Sound Chamber™ Technology
Acoustic Sound Chamber technology is used in the nozzle section. The use of a concave tubing system at the nozzle tip prevents sweat and foreign matter from entering the conduit.
- Equipped with German military grade 7-pin connector
It is equipped with a military-grade iridium connector made in Germany, which is easy to connect and disconnect yet allows for a secure connection. The connector is a "7-pin" type that cannot be pushed in unless it is inserted in the correct direction, preventing unexpected accidents during connection. In addition, the O-ring on the connector acts as a packing to prevent sweat and other contaminants from entering the connector.
4N silver-plated high-purity OFC cable with Variable Bass function
The cable is made of 4N silver-plated high-purity OFC for accurate transmission. It is the strongest, lightest, and most durable cable ever adopted. It is also habit-resistant and easy to handle. The "Variable bass" function, which allows the user to adjust the low frequency range (10Hz to 100Hz), is mounted on the cable, allowing adjustment according to the usage environment and personal preferences.
- Original Carrying Case
A machined, rugged aluminum flip-top carrying case is included.
- Handcrafted IEM Made in the USA
Manufactured in Orlando, Florida by the same talented engineers and technicians who produce JH Audio's line of custom IEMs that support thousands of professional ears on stages around the world.
The JH Audio ROXANNE AION package meets the price standard.
However, it is not particularly impressive for an unusually expensive IEM.

- Carrying case
- Many eartips
- Manuals and warranties
The build quality of the exterior meets the price standard..
The fit is not bad, but not suitable for people with small ears. This still seems to be smaller than the previous generation, though.

Braking characteristics (effect of output impedance)
JH Audio ROXANNE AION is greatly affected by the output impedance of the amplifier. Playback on a dedicated digital audio player is recommended.

JH Audio's flagship JH Audio ROXANNE AION has the resolution and range of a high-end product, but the sound balance is not very good and the overall distortion rate is lacking.
The product is generally overpriced, at least in terms of audio specifications. A fair price in terms of sound quality can be estimated quite favorably at $200 at the most. Even so, it is still quite questionable.
The basic sound of ROXANNE AION is the so-called "treble happy sound" (high-frequency idiots), and by tweaking a screw in the middle of the cable, the sound can basically be adjusted in the low-frequency direction.
However, the adjustment of the high frequency range is too extreme, and although the clarity is high and delicate sounding, the sense of localization is easily adversely affected, and the balance of the music sounds basically disintegrated. The midrange texture reproduction is also terrible, making it totally unsuitable for enjoying classical music at least, and rock music with a poor dynamic range can be heard if you close your eyes to various aspects of the music.
It may not be bad for those who want to hear only the cymbal and snare sounds clearly, but no matter what kind of music you listen to, you will soon get bored with the overall sound because it is too crisp and flimsy.
Also, the high frequencies are too strong, so the grinding sound is not so noticeable and sharp, but the sense of burden is quite strong. If you like metallic sounds, it may not be bad.
If these earphones sound balanced enough, you might have high frequency hearing loss, so it might be a good idea to check for hearing loss.
