This is an upgrade cable optimized for SHURE earphones (MMCX, so it can be used with other brands as well). The carefully selected wires improve sound transmission, and the cable itself is flexible, making it a very user-friendly model. The length is 1.2m. Here are my personal impressions, as someone who handles many SHURE products: When listening to SHURE's higher-end models, I felt an enhanced high-frequency range, like a spray of water. If I were to compare it to existing products, it's similar to NOBUNAGA Labs. The models I used for testing were the SE215 and SE846, and I felt the same tendency with both. Re-cabling can often be expensive, but the changes you get at this price make it a very cost-effective product. Instant purchase is OK. The product is new and unused. Color: Silver Length: 1.2m to less than 1.5m
