I bought it half a year ago, but I've only used it a few times, so it's practically new! The sound quality is fine, and you can adjust the volume and audio settings, and make calls. There's almost no delay. The retail price is 2500 yen, but I'm selling it for this price! The first four photos are actual pictures. From the fifth photo, I've screenshotted the headphones' homepage. https://www.kenwood.com/jp/headphones/products/kh-kz30/
