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.

Very easy to use
Size: 12 Pairs / 24 pcs
I have an Onkyo audio/video receiver along with an Emotiva amplifier. Both have speaker "post" terminals which will accept banana plugs, OR I can connect the speaker wires by unscrewing the posts, poke the speaker wires into the terminals and then tighten the posts. The problem with poking the wires into the terminals and tightening the posts vs using banana plugs is that there is a risk of the wires touching the metal on the back of the chassis or touching other speaker wires, causing a short if one is not careful. With banana plugs, they simply plug into the back/top of the posts, eliminating the rsick of a short circuit. They can also be unplugged very easily if needed. Banana plugs are DEFINITELY the preferred way to connect speakers to an receiver or amplifier if they have post-style terminals. These particular banana plugs came in a package of 12 I believe. They were very reasonably priced, and simple to connect to the end of the speaker wires. Simply unscrew the banana plugs, use a small, standard jewelry screwdriver and loosen both of the set screws, insert the speaker wire, then tighten the set screws, and then screw the banana plug back together. The plugs have either a red band which would typically be used for your "Right" speakers, or a black band which would typically be used for the "left" speakers. The banana plugs insert into the top or front of the speaker terminal posts on the amp and receiver. They fit VERY snug, and so I did have to apply just a little bit of pressure in order to insert them into the posts, but once plugged in, rest assured they're not going anywhere. They are snug. I highly recommend these.
