I have a JBL Charge 3 that fell while charging breaking the USB connector off. These were a direct replacement and worked great to get an expensive speaker that is otherwise in perfect condition back up and running. Be cautious though, the soldering required to make these tiny connections is not for beginners and I'd recommend getting some help if you've never done it before. These connections are millimeters in size and very hard not to solder them all together. This is a result of the connector type and not this product so these are perfect. They're a little expensive especially since I only needed one but I guess I have a spare if it ever happens again.
