Works just as described. I bought this after my case stopped charging them properly and it saved me from having to buy a new set. It's also awesome that you can charge them one at a time.

Thought my bluetooth earbuds were broken but turns out it was the charging wire. This did the trick.

Product works exactly like it is supposed to. Allows me to leave a power chord at home and have one that I take everywhere else.
