Purchased in June 2025 from the official online store. This is a set including the wireless earbuds, charging case, and ear tips. Functionality has been confirmed, and there are no issues with pairing, sound quality, or other usage aspects. ※ These are the 'ATH-CKS30TW+' summer-oriented fully wireless earbuds, featuring powerful bass, noise cancellation, and water/dust resistance. There are faint scratches on the bottom of the case (see photo 5). They are not very noticeable, but please refrain from purchasing if you are concerned. I have used them with care overall, and they have been lightly cleaned with alcohol. I hope to pass them on to someone who is looking for them. Instant purchase is OK ☺️
