ご覧いただきありがとうございます。
SONYの定番モニターヘッドホン「MDR-CD900ST」を出品いたします。

外装をリフレッシュして使おうとメンテナンスを行いましたが、音質に気になる点があるため「訳あり・ジャンク扱い」として開始価格を下げて出品いたします。以下の説明を必ずお読みいただき、ご納得の上で入札をお願いいたします。

■ 商品の状態と「訳あり」の理由

動作: 左右両方のハウジングから音はしっかり出ており、断線等はなさそうです。

訳ありの理由: 個人的な感覚として、本来の音よりも少し軽く(スカスカに)感じられました。

考えられる原因: 出品にあたり、イヤーパッドを社外品(互換品)の新品に交換しています。パッドの厚みや密閉度の変化による音質変化の可能性が高いと考えておりますが、原因の特定はできておりません。

内部の状態: イヤーパッド交換時に内部を確認した際、ドライバー周辺のスポンジ等に経年劣化がみられました。

ケーブルの状態: ヘッドホン本体から伸びているコード部分、20センチほどの範囲に若干のべた付きがあります(写真参照)。アルコールや重曹等で清掃しましたが完全には取りきれず、深追いしてコードを痛めるのを避けるため、現状でのお渡しとさせていただきます。

■ メンテナンス箇所(外装は綺麗です)

【新品】イヤーパッド(社外品)に交換済み

【新品】ヘッドバンドカバー取り付け済み

本体全体:できる限りの清掃・アルコール除菌済み

■ 【おまけ】新品 3.5mmプラグ変換アダプター
通常のCD900STは太い6.3mm標準プラグですが、PCやスマホのイヤホンジャックでそのままお使いいただけるよう、オーディオテクニカ製の3.5mm変換プラグ(AT3C19Sa)をお付けします。動作テストに使用したのみの新品です。

■ 注意事項(必ずお読みください)
保管時はジップロックに入れており、音は出ますが、上記の通り音質に違和感・パーツの劣化があるため、【現状渡し・ノークレーム・ノーリターン】を厳守いただける方のみご入札ください。

ご自身で純正パッドに戻して試せる方、内部のメンテナンスが可能な方におすすめいたします。完璧な動作や本来の音質を求める方、状態に神経質な方は入札をお控えください。

■ 発送について
おてがる配送(匿名配送)にて、緩衝材で丁寧に梱包して発送いたします。

ご検討のほど、よろしくお願いいたします。

International Shipping Methods
Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters). After sending the email, notify us in the customer service message. We will confirm with the seller as soon as possible. and if there are any related questions, we will contact you through the customer service message. Thank you for your cooperation."

Please provide:
1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)
4. Photos of the product (Please include relevant descriptions to help us confirm with the seller)

Important Notes:
1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.
