Thank you for viewing. This is the Audio-Technica ATH-TWX9. Please be aware that this is a junk item. - Purchased around the release date. - The charging case shows considerable signs of use, but works without problems. - The left earbud works without problems. - The right earbud has a problem. The audio cuts out with a high probability. - The included accessories have not been used and are complete. - I believe I replaced the ear tips with AZLA SednaEarfit MAX for TWS, but I'm not sure if it was TWS; I apologize. They are probably size M. I will include these as well. When I had it estimated for repair, it would probably have been less than 20,000 yen for a replacement. Lightly cleaned. Despite this condition, please understand and purchase accordingly.
