Thank you for viewing. I am selling OnePlus Buds 4 (wireless earphones). Supports multi-point and LHDC. *LHDC is unconfirmed as I do not have a compatible smartphone. *LDAC is not supported. Please be aware. Although it is a Chinese model, the app supports Japanese. Also, there were no announcements for mode switching originally, and notifications were via sound effects, so there were no issues. ANC is rated at -55dB. I felt it was stronger than the Anker Soundcore Liberty 5 and Earfun Air Pro 4i in terms of experience. --- ◆Product Condition Usage period: Approximately 2 months *About once a week There are no noticeable scratches or stains, and the overall condition is good. All accessories are complete, and the original box is also included. Pairing with Android and iPhone: ok Audio playback: ok Microphone calls: ok Tap operation: ok Case charging: ok ◆Accessories OnePlus Buds 4 main unit (earphones x 2) Charging case USB-C charging cable Eartips (size M are already attached to the main unit) Instruction manual Original box Although it is a used item, I have handled it with care.
