I purchased this item on sale in July 2025 for ¥19,990. I'm selling it because I've only used it two or three times. There are no particular accessories. You can charge it using your own USB-C cable. Here are the product details from the website: ────────── 【Up to 35 hours of continuous playback & both wireless and wired】The wireless headphones have a 500mAh large-capacity battery, and the power-saving design allows for up to 35 hours of continuous use on a single full charge. You can listen to over 300 songs. Wireless connection applies to over 99% of Bluetooth devices on the market. You can also connect to devices such as PCs, computers, tablets, and smartphones using the included 3.5mm audio cable for wired connection. You can connect even if the battery runs out or if the device doesn't have Bluetooth functionality. 【Bluetooth 5.4+EDR stable connection & Hi-Fi high-quality sound, low latency】The headphones use the industry's highest-class Bluetooth 5.4+EDR technology, which minimizes sound skipping, and achieves wider, faster, lower power consumption, and more stable and seamless connections. The lag between video and audio during video viewing is also significantly reduced from the previous model, allowing for a smooth gaming and video viewing experience. 【Easy button operation & ANC noise canceling】You can control "music play/pause, skip forward, skip backward, answer/hang up/end calls" with just the push of a button. The product is equipped with an ANC noise-canceling function, which blocks out unwanted surrounding noise, allowing you to concentrate on studying or working.
