The most legit banana plugs I could find on Amazon
Size: 6 Pairs / 12 pcs, Size: 6 Pairs / 12 pcs
NEW PREFACE:: I am kind of glad I first bought the horribly magnetic, horribly made and GOLD PAINTED Sewell crimp on plugs (some reviewers say that Sewell are better and easier to use than the FosPower, which is true in design, but in quality of materials FosPower beats them hands down!!) ... Changing from those to these FosPower plugs plus the Monoprice 90° plugs, I am flabbergasted at the difference they make in sound quality. I have heard people say that they can hear the difference and even as an audiophile I was skeptical..... but my skepticism has been completely erased by what I am hearing with my own ears. I waited a few days to make sure I wasn’t just tripping before updating this review 🤣....but it has become clear to me how much a difference plugs made from the right materials actually make!!! I am 100% serious that the bass coming out of my Polk Signature Series tower speakers has at least doubled at the same volume. I can also now turn the volume up Way past my max volume before, without any distortion and much more clarity and less harsh highs. Everything just sounds warmer in general now which is amazing!!!! This is dangerous info for me... because now I’m thinking about making some really nice custom wires to see how much of a difference that makes 🙄🙄🤣 OK onto the review of the actual plugs here~~
These seem like decent connectors. I can’t tell if they are brass or copper, but they only have a slight hint of a magnetic property when testing them with a very powerful magnet. I was easily able to fit x2 - 14ga wires into it for bi-wiring purposes, including screwing on the collar. (As seen in my example pic) The gold plating on the tips seems legit and not painted like some of the plugs from Sewell... I have tested and tried quite a few plugs from Amazon and most seem to be crap. These however hold up better than most! These and the Monoprice 90° banana plugs with the black and red rubber sleeves. The latter are gold plated copper and have zero magnetic properties. (if you need 90° banana plugs)
UPDATE: still the best plugs I have found, but upon full install found two issues. One is a defect where a set of the plug threads for the barrel cover body weren’t cut right. The body’s do not tighten and stay loose because of that. Obvious issue for vibration with metal on metal...
The other issue is that even though these say they can fit different gauge wires, they seem to be geared more towards 12 or 10 gauge. I am using semi solid strand 14 gauge and find that unless I fold the wire over to make it double thick, the bolts use up all the thread and seem to become kind of loose inside the body. They won’t fully seat and keep spinning no matter how much you tighten. They seem to stay secure still but I just wonder about longevity over time with vibrations. So I just doubled up the wire and they seated fine! Not the worst issue in the world, but just kind of a pain since you have to strip the wire longer than you normally would so you can fold it over.
ANOTHER UPDATE: I had to remove these plugs from the wire to connect them to a crappy spring terminal amp while my better amp was in the shop. The issue I wrote about with the set screws "bottoming out" on smaller gauge wire became a more pronounced issue! I could not unscrew the set screws anymore and just had to cut the wires... So that means I will need to purchase more of these to replace the ones I cannot get wire back into. Not the best design, but still one of the best plugs I have found on Amazon.

Sturdy. Tight fit. No wobble
Size: 2 Pairs / 4 pcs
These are the best ones I’ve found. This order will connect one wire. Luckily that’s what I needed. If you’re doing more than one wire…

Superior Design!
Size: 6 Pairs / 12 pcs
Delivery was lightning fast.
I tried a pack of two pairs of these banana jacks as a sample to see if these would meet my needs. The design of these plugs is superior. The design was exactly what I wanted because the speaker wire is secured with TWO set screws. Then I ordered an additional six pairs of plugs to hook up my subwoofer to my amp and speakers.
(I feed the audio output from the amp to the sub. The sub has a crossover that keeps the low frequencies and sends the mid and treble frequencies to my bookshelf speakers.)
I love the security of two set screws on each plug and love the barrel that screws on AFTER the wire is secured by the set screws. Most banana plugs have a hole through the shaft of the plug that receives the stripped wire. Then the barrel cover is screwed down to secure the wire in the plug. This design compresses the speaker wire but eventually the cap loses it grip and allows the connection between the wire and the plug to become loose. Then the transfer of the audio signal becomes poor and the speakers sound bad. Every month or two I needed to check all the banana plugs and re-tighten many of them for the best performance. The two set screws eliminate this problem. The set screws are quite small and take a little extra care in installation. You will need a small flat blade screwdriver to tighten them. I used the 1/8" flat blade driver from a set of jewelers screwdrivers.
These well made plugs are a bit pricier that many of the banana plugs available but certainly not the priciest plugs available. For me, the slightly higher price was more than offset by the security of the wire within the plug.
I'm not thrilled with the extra tight fit of the tip on the plugs into the jacks. It took a lot of effort to insert the in the jack. Actually I "greased" the pins (very sparingly) with with non-corrosion, conductive paste (Ox-Gard, No-Corrode, etc. Do NOT use any other grease.) Next time I'll use pliers to compress the pin.
My only quibbles are that the spring pins that go into the jack are very tight and that the plugs are only sold in quantities of two pairs or 12 pairs.
I recommend these banana plugs for all who are using the banana plugs and jacks for hooking up your speakers. It's a very convenient way of connecting speakers if your speakers and amplifier have the banana jack as part of the binding post. Further, it's much safer to use banana plugs since the possibility of shorting your amplifier with a stray strand of wire is practically zero. Easy Five Stars.
