Review on 💻 4-Pack Ancable TRS Male Plug 2.5mm Solder Type DIY Audio Cable Connector for Repairing Headphones and Headsets - Stereo 3 Pole by Fernando Wolford

I hate to give a bad review, but all four connectors are bad. The tests are good at first, but after soldering the wires to the terminals (terminals), there is no connection between the tip (center contact) and its terminal. I know that too much heat can melt the plastic, but no matter how carefully I solder, the tip no longer connects. My guess is that at the tip is a long needle with a nail-like head, and the point for the tip lies loosely under the "head" of the "nail". But the slightest heat softens the plastic so much that the connector weakens and no longer touches. I was able to add more solder to restore the electrical connection between the terminal and the tab, but this melts the plastic and is not a reliable connection.
