This is a collaboration product between Ao no Hako and Onkyo. Please refer to the photos for the included accessories. Retail price: 15,000 yen (see official photos) This product was opened once for operational check and then tested once, but the sound quality was different from what I expected, so I am selling it. Confirmed on 2025/12/22. I try my best not to touch the product, but if you are particular about the condition and are sensitive to initial scratches, very minor scratches on the outer box, dust, etc., and expect a completely new condition, please refrain from purchasing and purchase from other sellers. Shipping will be done using the packaging materials that it came with, and will be sent via anonymous delivery. Thank you for your consideration. #Aonohako #ChikaKano #Earphones #onkyo #cp-tws01 #WirelessEarphones
