Hello there, everyone!
I decided to make a thread about Crosszone headphones, since we ain't got any so far.
Those are high-end headphones from Japan, with interesting technologies.
So far, I know they have two models, the CZ-1 and the CZ-10.
Here's some info about each, from the official pages:
Crosszone CZ-1
Crosszone’s CZ-1 is a unique headphone that achieves the External Sound Localization effect with an original technology. Different from conventional headphones that have a problem known as internal sound localization (in which the sound sources seems to be located inside the head), the CZ-1 uses Acoustic Resonance Technology (ART) and Acoustic Delay Chambers (ADC) to achieve this natural and spatial sound field. It simulates the experience and sound pathway listening with stereo speakers.
Three different pathways are created using ART and ADC technology. Two drivers (for high and low frequencies) create the direct sound. Another 40mm driver creates the reverse channel sound. The two air chambers for mainly the reflected and reverse sounds are used to create this delay. Sounds from the reverse and reflected chamber are mixed with the direct sounds, which generates a spatial sound field and a wide sound stage (external sound localization).
In order to fully experience the forward staging effect, we recommend that you place the ear pads closer to the back of your ear.
Actualization of Natural Sound Quality and Good Balance of Sound Frequency
As the diaphragm plate on the two driver units for the main sound sources (Tweeter 23mm/ Woofer 40mm) is coated with beryllium and the brass frame is adopted for the woofer driver, the balance of natural sound is well reproduced from lowest to highest frequencies.
Dedicated Cables to Support High Sound Quality and High-Resolution
High quality cables are provided with the CZ-1. The OFC (oxygen free copper) cable features an anti-noise, twisted structure. 8 cores (4×2) are separated from the plug at the amplifier side, which assures left-right channel separation. The housing cable connector has a waterproof structure; sound quality variation due to air leakage is well controlled.
The cables can be connected to either the left or right earpiece as channel integrity is maintained. This feature also reduces wear and stress on the cable and headset.
Acoustic Resonance Technology (ART): phenomenon in which an acoustic system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration.
Acoustic Delay Chamber (ADC): Crosszone’s chamber design technology using sound pipes generating opposite sound and sound ducts that create reflected sound to achieve out of head localization.
ART and ADC technologies used in the CZ-10 model create three unique pathways, with the drivers producing the initial sound. A 35mm driver then reverses the channel sound. The CZ-10’s two air chambers create space for the soundwaves to reflect, generating an intended delay. The headphones’ unique design allows these three pathways to be mixed outside of the ear canal, resulting in a naturally created a spatial sound field.

Crosszone’s CZ-8A is a unique headphone that achieves the External Sound Localization effect with an original technology. Different from conventional headphones that have a problem known as internal sound localization (in which the sound sources seems to be located inside the head), the CZ-8A uses Acoustic Resonance Technology (ART) and Acoustic Delay Chambers (ADC) to achieve this natural and spatial sound field. It simulates the experience and sound pathway listening with stereo speakers.
CZ- 8A continues to optimize ART (Acoustic Resonance Technology) and focuses on wave front control that minimizes the influence of differing ear shape to sound, further enhancing the external sound localization effect. The sounds emitted from speakers spread out as spherical wave fronts at first and gradually become planar as it gets closer to the listener. These plane wave fronts allow us to determine the direction and distance of sound.
However, with headphones, the sound source is very close and reaches the ear in the form of spherical wave fronts. In the CZ-8A, a wave front control guide is devised using the principle of acoustic lens, which delays the sounds and adjusts the wave front reaching the ear. The external sound localization presents an even more natural sound field and sound image.
The main channel contains aΦ40mm low frequency driver unit and a Φ23mm high frequency driver. AnotherΦ35mm cross-feed driver is for the opposite channel sound. Each driver is beryllium coated to ensure uniform and smooth sound quality. In addition, a brass ring is attached to each unit frame to increase strength and eliminate unnecessary vibration.
The standard accessories of CZ-8A include two OFC cables; 1.5 m (with Φ3.5mm small plug)and 3.5m(with Φ6.3mm standard plug)in length, which can be easily mounted to any portable players and amplifiers. The solid, spiral OFC cables have strong anti-noise capacity. To ensure the separation of the left and right channel signals, the connecting cables have 8 separate wires (4 wires * 2 sets).
CZ-8A ear pads are 3D designed – with different thickness front and back. Coupled with the curvature on the baffle close to the ear, the ear pads fit comfortably to the head without discomfort, leading also to a stable reproduction of low-frequency sounds.
The CZ-1 and CZ-10 has an ADC (Acoustic Delay Chamber) that delays opposite channel sounds, designed on the outer cover of the headphone. CZ-8A places the ADC within the cover, wrapped with aluminum. The shielding effect of this cover reduces the effect of electromagnetic noise on the drivers and allows for a clear and detailed playback of sounds.

Crosszone CZ-10
Features
Natural Resonance
Like the CZ-1 model, Crosszone’s CZ-10 headphones use innovative technology to reproduce and externalize sound’s location. While conventional headphones internalize sound by directing it straight into the ear canal, the CZ-10 utilizes state of the art Acoustic Resonance Technology (ART*) and Acoustic Delay Chambers (ADC**) to create natural resonance outside of the ear, resulting in a fuller sound stage and improved spatial audio. The result produces fluid movement of audio and soundwaves to recreate a two-channel speaker listening experience.Acoustic Resonance Technology (ART): phenomenon in which an acoustic system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration.
Acoustic Delay Chamber (ADC): Crosszone’s chamber design technology using sound pipes generating opposite sound and sound ducts that create reflected sound to achieve out of head localization.
Quality by Design
Organically Balanced Sound
Beryllium coats the diaphragm plates on the CZ-10’s two driver units, with a brass frame encasing the woofer. These distinctive alloys naturally balance sound from the lowest to the highest frequencies providing superior sound reproduction and performance.ART and ADC technologies used in the CZ-10 model create three unique pathways, with the drivers producing the initial sound. A 35mm driver then reverses the channel sound. The CZ-10’s two air chambers create space for the soundwaves to reflect, generating an intended delay. The headphones’ unique design allows these three pathways to be mixed outside of the ear canal, resulting in a naturally created a spatial sound field.
High Class Cables Complete your Experience
The CZ-10 headphones include complimentary high-end cables to round out your listening experience. The Oxygen Free Copper (OFC) cable used, features a twisted, anti-noise structure. 8 cords (4x2) are separated from the plug at the amplifier end, ensuring left-right channel separation. A waterproof housing cable connector prevents air leakage which helps produce consistent uncompromised sound quality. The separation of the cables on the channel end allow for either side to be conveniently used in the left or right earpiece. This design further reduces everyday wear and tear on the headphones themselves.Comfortable Fit and Form
Traditional spring-loaded headband designs of conventional over-the-ear headphones can create undesired and unnecessary pressure on both sides of the wearer’s head. The CZ-10 features state-of-the-art torsion springs connected to the CZ-10 hinges that vastly reduce this unwanted tension. The result is a more comfortable listening experience from beginning to end.Robust Construction
The CZ-1’s headband core is crafted from sturdy die cast magnesium, which retains its shape and is prized for its durability and resilience for long-term use and enjoyment for years to come.Enhanced Comfort
The unique triangular housing is a result of the tridimensional configuration of the three driver units.Sturdy Construction
The CZ-10’s headband is crafted from die cast magnesium, which retains its shape and is not easily deformed after long-term use.Lateral Pressure Relief
The springy headband design of conventional over-the-ear headphones creates direct pressure on both sides of the head. The CZ-10 features torsion springs built into a hinge on either side that reduces this tension to allow for a comfortable listening experience.Effect Linearity and Low-side Pressure
By fundamentally reviewing the general side pressure mechanism and devising a mechanism using high stiffness of the head band and spring pressurization, we were able to obtain comfortable side pressure with little differences between individuals.Specifications
