Technics' (Technics) top-of-the-line, fully wireless earphones EAH-AZ100-S (Silver). I lost one earbud (1 earphone) shortly after purchasing, so this is a listing for only one earbud. The remaining earbud has no issues with sound or connection, and the sound quality is normal. There is no noise or sound cutting out. I've only used it a few times since then, and both the main unit and the case are in very clean condition. I will also include a rubber protective case that I purchased separately. Since this is a used item, please refrain from purchasing if you are looking for a complete set or are very particular about condition. ◽️Product Information◽️ Product Name: Wireless Stereo Inside Headphones EAH-AZ100-S Brand: Technics Color: Silver Wearing Style: Fully Wireless (Left and Right Separate) *One earbud only Earphone Type: Canal Type Connection Method: Bluetooth Driver: Dynamic Type (10mm) Charging: USB Type-C / Qi compatible Charging Time: Approximately 2 hours Weight: 11.8g Notes (Important) *This product is for one earbud only. *Sound and operation have been confirmed (no problems). *Returns are not accepted to prevent swapping.
