#Halloween on Mercari (Bluetooth 5.3 Wireless Headphones) [Up to 65 hours of music playback / Ultra Noise Cancelling 2.0 / LDAC/Hi-Res compatible (wireless/wired) / Multipoint connection / External sound capture / Built-in microphone] Thank you for viewing. I purchased these new and used them for about 3 days, but I'm selling them now as I no longer use them. There are no noticeable scratches or stains on the main unit, but please understand that this is a casual inspection, so there may be oversights. A case is also included, but as you can see in the photo, there are some marks on it. There is no problem with use, but please refrain from purchasing if you are concerned. Operation has been confirmed, and it can also connect to the dedicated app. If you have any requests for additional photos, please feel free to comment.
