Review on 20 Pack 1/4" 90 Degree Angle Plugs TS Mono Heavy Duty Style for Speaker Cables, Patch Cables, Snakes - Male 1/4 Inch Phono 6.3mm Phone Plug Bulk: High-Quality and Versatile Audio Connectors by Naomi Snyder

So a plug is a plug right? Not correct! I figured all the connectors were basically the same, so I went with them as they were the cheapest option at the time. One was missing a back. Some of them were flawed from the start. Half of the rest failed after soldering (no problems with soldering or extra insulation I use, just a slight bending of the connection points during assembly caused internal shorts). In addition, the actual conductor resistance is higher than that of quality connectors (sometimes >10 ohms). Poor material quality, poor construction and poor quality control. If you don't enjoy spending hours troubleshooting shorts, DO NOT BUY THESE CONNECTORS!
