This is the left earbud for the AirPods Pro (2nd generation). The model number is A2699. It's a Lightning-type earbud. This is the MQD83J/A model earbud. Genuine Apple product (domestic version). It has been used infrequently and is in good condition. This is a guaranteed authentic product, so please feel free to purchase with confidence. Operation has been confirmed. It functions normally, including all features. Noise cancellation works perfectly. Also, there is no noticeable battery degradation, so I think it can still be used for a long time. This is a single item, the left earbud only. Please only purchase if you are able to pair it. I would like to sell it quickly. I mistakenly purchased an A2699, thinking it was an A3047. Price negotiations are possible, so please comment.
