・This is a so-called Chinese DAP (Digital Audio Player). It supports DSD256 and PCM384/64 natively, full MQA decoding, Bluetooth 5.0, AirPlay, and a 2.5mm balanced output jack. ・It runs on HiByOS, which is specialized for music players instead of Android (the overall build quality feels somewhat lacking, which is typical of Chinese products), so the operation itself is smooth. ・In terms of sound quality, it's characterized by a strong, powerful sound and sharp resolution. ・Regarding the main unit, it functions without any problems, but the display has a chip and cracks. There are also minor scratches and blemishes consistent with use. Please be aware of this when purchasing. ・Price: Approximately 22,000 yen ・The items included are the main unit, original box, cable, case, pouch, and instruction manual.
