[Tone Chamber System to Enhance Earphone Housing Resonance] We have newly developed a "Tone Chamber System" that unlocks new possibilities for BA drivers. By creating a special acoustic space in front of the driver, we utilize the inherent acoustic characteristics of the BA driver while also bringing 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 inside is limited to only a very small amount that does not affect sound quality, and the rest is assembled without adhesive. [Two Full-Range BA Drivers in a Horizontal Opposite Arrangement] This earphone features two full-range BA drivers. Since it's desirable for the two drivers to have as similar acoustic characteristics as possible, they are paired using stricter criteria than usual. Furthermore, the two drivers are arranged in a horizontally opposed configuration, which cancels out internal vibrations, suppressing unwanted resonance within the drivers themselves. These drivers are also fixed within the housing without adhesive. [High-precision machined stainless steel enclosure] The enclosure is constructed from parts that have been precisely machined and blast-finished from highly rigid stainless steel. Compared to the brass enclosure of the S5000, it features a sharper, tighter, and more direct sound. [Designed with optimal fit as the top priority] In addition to the standard wearing method, the cylindrical design also supports over-ear wearing. By slightly inward-angled the joint between the housing and the cable connector, the cable fits more easily to the body and touch noise is further reduced. [Next-generation ear tips FUSION-G included] Three sizes of the next-generation ear tips "FUSION-G" are included. These ear tips feature a triple hybrid structure combining ultra-dense foam, soft silicone, and high-elasticity silicone, achieving both high sound isolation and a comfortable, non-pressure fit. [Soft Silver Coated Cable Included] The included cable is made of 8-core silver-coated OFC wire braided together, making it soft and easy to handle. The 2-pin connector is a high-precision, in-house developed product and conforms to the most versatile φ0.78 standard. Featuring a "Tone Chamber System" that unlocks new possibilities for BA drivers, this earphone boasts a sharp, clear sound thanks to its stainless steel housing.
