Technics AZ80-K Replacement Mesh Sheets 【PNYSAAZ80】! Purchased from the official Panasonic store♪ There are types A and B for the mesh sheets, and this is type A. We recommend confirming which type is compatible with your earphones before purchasing☆ Just a personal experience, but I had trouble hearing in one ear, and I thought I'd try replacing the mesh sheets before sending them in for repair! It was resolved surprisingly easily♪ (I felt a bit disgusted with myself, wondering if they were that dirty...) I will cut off one set of sheets with scissors, and send them in a separate zip-lock bag. I've set the price to be as low as possible, and the shipping method is "regular mail," which does not include tracking. For an additional 100 yen, you can change to "Yu-packet Mini" with tracking. Please let me know in the comments if you'd like to change the shipping method☆ I will then reconfigure the settings. No claims or returns accepted. I am also selling 【2 sets】 separately. Please take a look if you'd like♪
