This is the Astell&Kern HC3. Please consider the following points before purchasing: * Purchased used. * Lightning adapter is not included. * The first photo shows everything included. * There is some color fading on the corners and edges due to use. * It gets slightly warm during use (this seems to be a product characteristic). * Operation has been confirmed before listing. * Small white noise may occur depending on the smartphone model, although it is not noticeable when used with a PC. You can enjoy watching movies on your PC with high-quality sound. Thank you for your consideration.
