I thought I had lost the charging cable for my Jaybird Freedom Wireless Headphones but when I visited the Jaybird website I noticed that buying the charger was a bit was expensive. . I did a little research and found that the Mini B 8 pin cable fits the JayBird Freedom charging adapter. Suffice to say they did their job. I don't expect them to last for years, but I don't expect my Jaybird Freedom headphones to last forever either. Pros: Good replacement for the factory headphone charger. Disadvantages: none.
