Bare wire can be intolerable to work with. Banana plugs make a positive secure connection. These plugs are a touch bulky. Nice to not have to deal with small screws. Use as large of gauge wire as possible. The description says no unintentional disconnections. I beg to differ the bite of teeth aren’t as good as described. Used a 16 gauge pure copper speaker wire and a teenager taught me how secure the wire really is by tugging on the wire not the banana plug pulling the wire free. It does the job, it’s not the latest and greatest. If you need easy get these. If you want slim secure banana plugs buy the small screw type.

Fully gold plated inside and out! I initially got the amazon basic connectors for the same price, but was disappointed in the tiny burgundy positive label they had. It was also very dirty inside the connector and it wasn’t gold plated through out the connector. These are excellent in quality and have a bright red ban on the connector! You wont be disappointed and beats out Sewell connectors for the price!

Decent, but be careful of frequent use.

Size: 12 Pairs / 24 pcs, Size: 12 Pairs / 24 pcs

The looks are very nice, functional if left alone once assembled. After that I would leave them alone otherwise you risk the main male portion just coming loose of the housing, sound quality is decent, nothing to write home about, but again, not very durable. If they could fix that 1 thing, these would be very good buy and value, the rest of each plug is hefty and well made.

Perfect for guitar wire harnesses.

This is the first time I’ve used this type of wire for building and repairing electric guitars. These 22 AWG stranded silicone insulated wires are perfect for connecting control pots and switches. They are soft, flexible, and the insulation does not burn or melt back when soldering. The wire itself is tinned pure copper and solders with ease. I use a silver bearing solder which requires more heat than standard lead/tin solder. The silicon insulation handles the heat just fine without burning or distorting it. The wire is strong and durable, yet it strips back easily with a standard stripping tool. They are true to the advertised thickness of 22 gauge. I have used both traditional cloth insulated (pull back), and PVC insulated guitar hookup wire in the past. I will be using this silicon wire from now on. It is easy to work with and produces a very clean professional looking result.
