WAGNUS Frosty Sheep with a 2.5mm 4-pole connector, compatible with Layra, Roxanne, Lola, and other JH Audio 4-pin IEMs. It features a rare, now-discontinued, high-end CINQBES pure copper unplated competition model plug from Topre, which is no longer available due to the company's closure. This is a pure copper plug, unplated, from the top-of-the-line CINQBES model, offering a purer sound quality than even pure copper with silver plating. The cable is a "No Variable Bass Control" type, delivering a vivid sound as if a veil has been lifted. I've used it with Roxanne and Lola, and it pairs exceptionally well with Roxanne's rich and deep sound, enhancing the resolution. Although there's no bass adjustment, I didn't feel any lack of bass. Combined with the pure copper plug, the sound is incredibly vivid, clear, and lifelike. After going through dealer-exclusive one-off cables, I arrived at this cable, and my IEMs have reached their full potential. I haven't experienced any issues with normal use, but I'm selling it due to a system change. While there are no issues with sound or functionality, the cable jacket has some discoloration and the plug shows some wear, so I've priced it considerably lower. Please refrain from bidding if you are concerned about these two points. ＜Specifications/Options＞ ・Plug: "Topre CINQBES Pure Copper Unplated Plug" (2.5mm 4-pole) ・Aurora Artwork ・JH 4-pin type (L-shaped clear shell / No Variable Bass Control) (This artwork alone cost an additional 20,000 yen including tax.

Based on "Sieve Sheep," which is becoming a legend, using the ultimate wire from the 1950s, and pursuing modern technology, the new flagship cable "Frosty Sheep" was born as a modern version of "Sieve Sheep." The structure is the same, with 60 cores and a thicker wire diameter of 0.08mm. Furthermore, the copper wire uses class 1 OFC, which boasts the highest purity among OFC (oxygen-free copper). All 60 cores are luxuriously pure silver plated and double silk wrapped.
