Thank you for viewing this product. This is the Anker Soundcore Liberty 4. I've used it for about six months. I mainly used it when I was out and about, so there are some minor scratches, but there are no noticeable scratches or problems with use. Regarding the specifications, please refer to other pages or the official website for details. The sound quality, noise canceling, and other features are excellent. This is an offer without the box and accessories. It's just the main unit, so I'm offering it at a low price. If you need them, I can provide them for an additional 1000 yen. I will include a cable so you can use it right away. I'm including the M-size ear tips. Thank you. - Color: Black - Design: In-ear - Case Shape: Compact charging case - Features: Wireless connection - Characteristics: Smooth sound quality - Compatibility: Bluetooth compatible Other features: Noise canceling
