Unused SENNHEISER ACCENTUM True Wireless (BLACK). From the flagship MOMENTUM series, by reducing some features, you can get high-quality Sennheiser sound at a lower price. Even though some features are reduced, I think this is a wireless earphone that basically has almost everything you need, such as external sound input, active noise canceling, aptX, LE Audio, Auracast support, multi-point connection, wireless charging, and waterproof/dustproof. I think you can enjoy it even with the AAC-compatible iPhone series. I sent it in for repair and it was exchanged for an unused item, but I had already purchased another product, so I am putting this up for sale. According to the manufacturer's warranty, "Replacement products may be unopened, or may be refurbished products that have been supplemented with damaged boxes or missing accessories." Please purchase only if you understand this. Returns are not accepted to prevent product substitution.
