Yongse, A-melody, whose crowdfunding campaign concluded last December (https://ubgoe.com/projects/1009). This is an earphone cable that significantly enhances sound resolution and transparency by utilizing Air-shield technology to block external noise and insulate the internal signal path with an air layer, keeping it clean. Brand new and unopened. I am selling it because I no longer have the opportunity to use it due to equipment upgrades. Configuration: 4-core (copper-silver alloy x 2 [silver content 4%] + pure silver x 2) Length: 120cm ±3cm Cable slider: None Plug/Connector Specifications: ① 0.78mm 2Pin / 4.4mm plug Cable only. Overall, it is in beautiful condition, but as it has been in someone's possession once, please refrain from purchasing if you are concerned about this or if you are looking for a perfect item. I will ship it within one day of purchase in principle. Please feel free to ask if you have any questions. Instant purchase is available. ── ── ── Search terms: a-melody a melody re-cable balanced connection
