"God earphones" created by the god of earphones! Listen to JH Audio "ROXANNE AION" with the popular high-resolution DAP

Are readers familiar with “custom earphones”? Custom-made earphones that are customized for optimal fit and sound isolation by collecting the user's ear mold.

It is said that custom earphones were originally created to protect the ears of musicians and engineers who support performances and productions from the risk of hearing loss. Custom earphones are now used by many musicians to monitor the "feedback" of their own voice and musical performances on stage where the sound is roaring.

Using state-of-the-art molding technology to reduce the size of the main body and significantly improve the comfort

Jerry Harvey, the founder of JH Audio, who has worked on all products, is a custom-made " He is respected by many music producers and audiophiles as the "god of in-ear monitors." JH Audio, which bears the initials of Mr. Jerry Harvey, has produced many famous earphones since the establishment of the brand. "ROXANNE", which was released in 2013 and landed in Japan in 2014, is a representative example of this.

This is a multi-driver configuration earphone with 12 BA drivers on each side. I am amazed at the craftsmanship that has been housed in a compact shell (housing) while installing four drivers each for the high, medium and low frequencies. By making full use of printing technology, we have taken a bold step toward miniaturization by further eliminating unnecessary internal volume.

In the shell, if you follow the tip of the nozzle in the opposite direction, each driver unit is mounted at a different distance. JH Audio's core technology is "freqphase," which realizes a sound with a sense of unity by perfectly matching the sound phase at the nozzle exit, even though it is not evenly spaced. It is one of the secret techniques that Mr. Jerry Harvey acquired from his many years of earphone development experience.

The optimally shaped shell designed by a 3D printer, named "Sonic Tube Chassis", was reborn as AION with new materials. Hundreds of carbon fiber fabrics are layered while injecting resin, and the shell is carefully polished on the outside to create a lightweight and highly rigid shell. The white and black marble-like shell faceplate has a pearly texture, and the chrome brand logo is proudly placed.

A space named "Acoustic Sound Chamber" is provided at the tip of the nozzle to prevent perspiration and foreign matter from entering the sound pipe. German military grade iridium metal connectors are used on the detachable cable side. As a 7-pin type with a fixed direction, a ring-shaped cap is attached to the base side to prevent moisture such as sweat from entering. It is an extremely stable connector that can be attached and detached smoothly and provides a stable grip. The screw-type locking mechanism that ROXANNE used for connectors has been discontinued.

The wire material of the detachable cable is 4N silver-plated high-purity OFC (oxygen-free copper). It can be bent flexibly, so it is easy to handle, lightweight and durable. In addition, ROXANNE continues to be equipped with the familiar bass adjustment function. By turning the dial using a minus-shaped mini driver, you can obtain the desired low-frequency balance for each of the left and right earphones. If the 5 o'clock position of the clock is the maximum bass, the position of about 3:30 gives a bass that fits any type of music. The connector on the player side is a 3.5mm unbalanced specification.

I tried listening with AK's limited high-resolution player "LUNA SEA 30th Anniversary Model"

Jerry Harvey mentioned the new product in the explanation video of ROXANNE AION published on YouTube. As for the sound, "The original ROXANNE has inherited the dynamic and realistic sound that has been well received by many audiophiles and musicians. It is a satisfying earphone that pursues a smaller size and a more comfortable fit. ” says.

This time, I rented a high-resolution player "SA700 LUNA SEA 30th Anniversary Edition" released by Astell & Kern, a limited production of 500 units made to commemorate the 30th anniversary of the formation of LUNA SEA, and listened to ROXANNE AION. rice field. The 30th anniversary logo of the band is laser-engraved on the back of the player. It is a luxurious player with special specifications that the same logo lights up on the screen when the power is turned on.

I listened to the 96kHz/24bit high-resolution sound source of aiko's representative song "Kabutomushi". Enchanted by clear and clear vocals. You can feel the fluctuation of the vibrato and the vivid breathing of the breath deep in your ears, and it will make your spine itch. There is depth in the scene created by the sense of distance between the band's performance and the vocalist. You will be drawn into the realistic scene of the stage and hall where the music is played, so much that you will forget that you are listening to the recorded sound source.

Since these earphones have a very clear reproducibility, I am an honest person who honestly draws out the ability of the player and the quality of the sound source. When listening to and comparing the same song with ROXANNE AION on a smartphone and Spotify, the power and resolution are unsatisfactory, and the reality of the music reveals a clear difference in ability. It's not the earphone's fault, so I'm sorry. JH Audio's latest model, which exposes the power of the source, is best enjoyed in combination with a talented player like the "SA700 LUNA SEA 30th Anniversary Edition".

This time, I also forgot that I was interviewing and listened to my favorite songs from end to end on ROXANNE AION. Hats off to her true strength. I want this But about 300,000 yen requires a drastic decision. Approximately 470,000 yen including players. However, if you plan to have a one-of-a-kind audio system that you can enjoy while loving it, it may be a great deal to get your change.
