Sewell Deadbolt RCA Plugs, 4 Pairs, Fast-Lock Technology, 24k Gold Plated Speaker Plugs, Premium Solderless SW-32888-4

Reasonably easy to use. You need to strip a little more length than usual as the strain relief hole may not fit over your cable. Easy to use the screws on the shielding and the main conductor although you need a very small tipped screwdriver. I had a set of jeweler's screwdrivers for tightening up my glasses and used one of those to loosen the screws and then tighten them down onto the connectors. Well made.

Painters broke my plug off at the subwoofer. Super easy fix with the instructions included. You will need a very small screw driver. Very pleased.

I bought these for coax, RG-8x is a good fit. Once assembled, it appears strong and a solid connection to an RCA jack.The cons are that they are somewhat difficult to assemble, and it is a good idea to have a (cheap) set of jewelers screwdrivers. The tiny screw for the center conductor is in a thin wall tube, and the screw only engages two or three threads. I stripped one, with not much torque. Soldered it. If the barrel were a millimeter or two longer, there would be more room for a thicker tube and larger screw. Also, I tried using common speaker wire, with poor results.By the way, there is an amazing amount of misinformation on the internet about coax for audio. The most common is the claim that the 50 or 75 ohm coax is not a good match for 8 ohm speakers. Total nonsense in two ways. First, the characteristic 50 ohm impedance only applies at high frequencies, where the wavelength becomes comparable to the cable length. The second nonsense is that speaker wire is also a transmission line with a characteristic impedance, about 70 to 100 ohms or so, even worse match to your speakers. Remember TV twinlead to your antenna on the roof? It was 300 ohms. There is more.On the positive side, coax has much lower inductance than speaker wire. Less phase shift at high audio frequencies. Also, the resistance of the shield is much less than the 16 gauge center conductor, so half the resistance for the same length. Also btw, a search for coax shield resistance produces an AI answer of 10 ohms per foot. Ridiculous.Moral: Don't get your information from chat rooms, or wire sellers. There are good technical descriptions available.Also, five stars for Amazon. I got plastic baby bowls instead of RCA plugs (!?), and a text chat with Amazon had replacements in my hands in less than 24 hours. Many thanks.

Hard to use . Little screws felt like i was building a watch. The opening was 2 big and the screw would fall out the bottom before it was tight . Used it for car audio . Maybe better for band equipment with larger wires .

I read that these were "an often returned item". I can understand why but it's not because of poor quality or manufacturing. They can be a little difficult to use because the screws are very small. I just bypassed the screws and soldered everything together. Made up some nice shims on the back so the wires fit tighter with my 3D printer and we were off to the races.

Unable to use.

This was perfect for fixing a damaged sub-woofer cable. Well-made product. Easy and quick fix.

Great idea, nice item, but the set screws are too short. And they will fall out if you are not carful. Made for tiny hands. The gold coating is so shiny I couldn't see what I was doing. Just glare. The set screw came out and no way my hands could even try to get the screw back in. So I threw them away. Time to get the solder gun out and buy standard RCA.
