These are locally-themed, re-cableable wired earphones from e-earphone Nagoya Osu store. They are made of brass and have a good weight to them. As someone who considers myself an earphone aficionado, I can vouch for the sound quality. It's not a typical "V-shaped" sound signature, but rather has a rich mid-bass and a natural sound that you can listen to for hours. As a bonus, a cable worth 10,000 yen (see photo 9, balanced output) is included. Please enjoy re-cabling them. - Brand: intime - Model Name: Shachi - Country of Manufacture: Japan - Earphone Color: Transparent/Gold - Accessories: Ear tips (multiple) Thank you for looking.
