3.5mm Screw Terminal Block Cable 3.5mm (1/8inch) Stereo TRRS Audio Male to 4 Pin/Way Female Bolt Screw Headphone Balum Converter Adapter Cable（30CM/2Packs) (4Pole/M)

These are extremely handy to have for initial speaker/mic testing since audio pinout standards for mic and ground can switch between some 3.5mm audio plugs. Using one of these to test out functionality before soldering up a tiny 3.5mm jack will probably save you some headaches. In my case, my son's gaming headset only had three physical wires in the cable. There was nothing else in the cable to separately carry a ground signal that I could tell with my multimeter, so it was a complete head scratcher as to how this was terminated up on the original 4-pole jack. None of the cable sheathing even had continuance. Unfortunately, our dog chewed up the jack, so I couldn't autopsy it to see how it was wired up. All I know is if I tried to jump straight into soldering without testing the connections on this, it would have been major frustration.

These are not elegant nor were they designed to be. I needed to protype something for a ham radio and this did the trick. Screws are good size and clamp plates lock wires fine. Good by me

An unnamed company used a proprietary 4 pin 3.5mm to 3 RCA plugs configuration for their overpriced cable. This made generic versions incompatible. I was able to reproduce the correct pinout using this adapter and some spare RCA cables cut and spliced for much cheaper.

I saw this item mentioned in a chat review and decided it would be handy to have in the tool box !! Looks very well done, and you get two of them. :)

I liked that the product worked...i disliked the product being delivered to someone elses home...and i used this product for pc testing...

Mein Kater findet es Super.

Parfait pour réparer la prise jack de mon ancien micro. Pas besoin de souder, juste dénuder et visser. Parfait.

I used this connectors to make an audio interface to a IPhone 3.5 socket.

Buen apaño para no tener que tirar los cascos por qué se rompa el jack,ahora vuelven a funcionar perfectamente .

The 4 pole 3.5mm jack plug to terminal block allows easy wiring and testing of various things that use this connector. Allowed me to connect up a microphone to my HP laptop for some tests, They supplied 2 cable assembly and a little flat blade screwdriver. All good.
