I was informed that there were some initial defective units that couldn't charge, so I only tested the charging, wireless charging, and functionality. There were no problems. I haven't put them in my ears. Since it's too large for a post-box, I will ship the main unit and accessories. If you'd like the original box, I can open it with a cutter to fit in the post box and send it. Please comment after purchase if you want the box. If there's no comment, I'll only ship the main unit and accessories. I have several in stock, so I can offer a discount on shipping if you comment.
