It's a black and white PI5 (Bowers & Wilkins). The battery lasts normally as it's been used for about a year. The connection isn't stable at first, but it becomes stable with use. This is a PI5, not a PI7. There are no accessories such as a box. Therefore, it's being sold at this price. Returns and exchanges are not possible. Also, the Hikonyan can is not included. I think this is a good deal for a high-end audio product from Bowers & Wilkins with noise cancellation at this price.
