Equipped with the "Tone Chamber System" to Enhance Housing Resonance
A newly developed "Tone Chamber System" explores new possibilities for BA drivers. By creating a dedicated acoustic space at the front of the driver, it enhances the natural acoustic properties of the BA driver while drawing out the resonance of the housing material. To ensure the precise functionality of this system, the internal volume of the housing is meticulously controlled. Adhesives are limited to a minimal amount in areas that do not affect sound quality, with the rest of the assembly being adhesive-free.
What is a Tone Chamber?
A tone chamber is a spatial design within the body of instruments like guitars to control resonance and tonal quality.
Dual Full-Range BA Drivers in "Opposed Placement"
This product features two full-range BA drivers. To ensure both drivers have nearly identical acoustic characteristics, they undergo stringent pairing processes beyond standard criteria. Additionally, the two drivers are arranged in an "opposed placement" configuration, which cancels internal vibrations and minimizes unwanted resonances. The drivers are also securely fixed inside the housing without the use of adhesives.
Precision-Crafted Stainless Steel Housing
The housing is made of high-rigidity stainless steel, precisely machined and finished with a blast treatment. Compared to the brass housing of the S5000 model, this delivers a sharper resonance and tighter, more direct sound.
Design Prioritizing Optimal Fit
The cylindrical design supports both standard and over-ear wearing styles. The angle at the junction between the housing and cable connector is slightly inward, ensuring the cable fits comfortably against the body and reducing touch noise.
Next-Generation FUSION-G Eartips Included
The included next-generation "FUSION-G" eartips combine ultra-dense foam, soft silicone, and high-elasticity silicone in a triple hybrid structure. This achieves superior noise isolation while ensuring a comfortable fit without pressure. Three sizes are included.
Soft Silver-Coated Cable Included
The included cable features 8-core silver-coated OFC wires, designed for flexibility and easy handling. The 2-pin connector, a high-precision in-house design, conforms to the widely-used φ0.78 standard.
Repairable Design for Long-Term Use
Unlike typical earphones where components are fixed with adhesives, making disassembly and repair challenging, the S4000 is designed to be disassembled with special tools. This ensures durability and long-term usability.
