I used these as a backup when my main wireless earbuds weren't working, but I'm selling them now since I don't use them as often. These are ultra-compact and lightweight wireless earbuds. They are no longer sold, and I think it's rare to find a set with all the accessories, including the box. I've confirmed they work, and I've also confirmed they fully charge. Please understand that the charging capacity may have decreased. ◾︎Product Specifications Playback time: Up to 5 hours (earbuds only) / Up to 20 hours (with charging case) *Playback time is for music playback and may vary depending on volume, content being played, and usage environment.
