3PCS 3.5mm 4 Pole Connector with Light Black Stainless Steel Metal Case for Headphone Repair - Gold Plating Aux Replacement Jack Plug for Soldering Stereo Audio Cable of Headset

the connector came with 2 poles not the same as writin or the picture

I don't suck at soldering and have decent equipment, but this was still challenging for a few reasons. 1. The ring that clamps the wire casing for strain relief is about 1mm from the first solder contact. This means that if you want to crimp your wire in, you have more or less zero tolerance. The second issue is that the outer barrel is so close to the solder joint that you have to make a tiny solder otherwise it will short. They provide some shrink tube to help fix that. Overall, if the barrel was 1mm wider and the ring 2mm further away from the end, it would make this WAY easier to work with.

This product is excellent, Just On Time, easy to install. Great seller
