Equipped with a "tone chamber system" that brings out the resonance of the earphone housingWe have developed a new "tone chamber system" that draws out new possibilities for the BA driver. By creating a special acoustic space in the front of the driver, we can take advantage of the inherent acoustic characteristics of the BA driver while drawing out the resonance of the housing material. In order for this system to function accurately, it is necessary to precisely control the volume inside the housing, so the adhesive used inside is limited to a very small part that does not affect the sound quality, and the rest is assembled without adhesive.
*Tone chamber is a spatial design applied inside the body to control the resonance and tone of instruments such as guitars.Image Name
Equipped with two full-range BA drivers in a "horizontally opposed" configurationIt is equipped with two full-range BA drivers. Since it is desirable for the two drivers to have as similar acoustic characteristics as possible, the pairing is performed under stricter standards than usual. In addition, the two drivers are arranged in a "horizontally opposed" configuration that cancels internal vibrations, suppressing unnecessary resonance of the drivers themselves. This driver is also fixed inside the housing without adhesive.
High-precision machined stainless steel housingThe body is made of precision-cut, blast-finished stainless steel parts with high rigidity. Compared to the brass body of the S5000, it features a sharper tone and a tighter, more direct sound.
Designed with optimal fit as a top priorityThe cylindrical design allows for a standard over-the-ear style wearing as well as a standard wearing style. The angle of the joint between the housing and the cable connector is tilted slightly inwards, making it easier for the cable to fit the body and further reducing touch noise.
Next-generation earpiece FUSION-G includedThree sizes of next-generation earpieces "FUSION-G" are included, which have a triple hybrid structure that combines three materials: ultra-density foam, soft silicone, and high-elasticity silicone, providing high sound insulation and a comfortable fit without any feeling of pressure.
Soft silver-coated cable includedThe included cable is made of 8-core silver-coated OFC wire braided for softness and ease of handling. The 2-pin connector is a high-precision product developed in-house, and uses the φ0.78 standard, which is considered to be the most versatile.
Repairable construction for long-term useMany parts of ordinary earphones are fixed with adhesive, making them difficult to disassemble and repair, and in many cases, products need to be replaced when they break down. The S4000 can be disassembled using special tools, and is designed for long-term use.
*Please do not disassemble or repair the product yourself, as this is not covered by the product warranty .
