I bought a couple sets of these plugs to hook up my existing speaker wire to a new Onkyo stereo system with speakers. They are easy to install and use with no tinning of the bare wires necessary. A very small screwdriver such as a jeweler's screwdriver is needed to tighten the two screws on each plug. As others have pointed out, place a cloth beneath the plug and wire you are working on because you probably will drop one or more of the tiny screws. The only downside: Rather expensive for what they are.

the Banana jacks were good 4☆ rating. only reason I give them 4 instead of 5 is because the rubber boot could have been a little longer.

This was my first time using them and the only reason I got them was because my speaker box had the female end installed already. These banana plugs were easy to install onto the wire even easier plugging into the female end. Also makes it easy too plug and unplug for whatever reason. They are quick, easy, and useful. Well worth it.

I’ve wired my last two homes with reams of copper speaker wire through walls and twisted up into the backs of receivers, where every few weeks or so, my leaning Tower of Home Theater gets bumped and of the twisted stalks of L or R surround wire gets pulled loose - I always wondered what thise gold conduits were on each terminal that seemed so inviting and sturdy and convenient... I’ve since moved to a wireless Atmos system but that’s beside the point - with these plugs, I was able to repurpose my aging Onkyo HD 7.1 receiver and Klipsch pro media speakers to realize crisp, punchy Dolby surround on my PC. These plugs were clutch because the klipsch speakers use clips, so the wire I had needed a different conduit to utilize those elusive terminals. Screwed the plugs into the wire, slid them into place on the receiver and bam! Ups and running in minutes. Felt a bit foolish that this solution has probably been around for decades, but a sound delay is preferable to dead air :p.

I needed a quick solution for speakers I purchased at the time. I did not want to wait for Amazon shipping (even though it’s free and fast). These were easy to attach than other plugs I purchased. I like the small size of these unlike many other plugs I used. I will end up using these when I decide to clean-up the wires connected to my receiver. Great product!
