uxcell 3.5 mm Audio Jack Connector PCB Mount Female Socket 4 Pin PJ-320A 15pcs

The pins take solder easy and the TRRS cord fits snugly. Using this for a split keyboard project and works well.

I replaced a 2.5mm aux jack on my Bose Quietcomfort 45 (QC45) headphones. I did this so it will be compatible with standard auxiliary audio products. It probably wasn't worth it over just using Bluetooth, but I wanted to see if I could, and it's the principle of having a good product. :) The jacks are good quality. I broke several jacks in the process, but that was my fault trying to force them into a very tight fit. It's a good thing this is a 10 pack!

These work very well, although they are a little tight for the first insertions. Also, the pinout shown in the pictures is incorrect. The Tip and 2nd Ring pins are reversed. The correct schematic for these jacks according to the print diagram labeling is attached to my post.

Good product

So for so good. Works! Not sure why buying more makes it cheaper. I’m new into fixing electronics having difficult time finding specific names and part numbers looking for a company or website that already has this figured out I want t type in a model number of an electronic or circuit board itself,. They can either have the print or the Parts list and I can order from that. Pricing is unique I needed one. The lowest I could order was 10, but it was cheaper to buy 15 not an issue. Just don’t know what I’m gonna do with the rest of them start stock piling circuit parts. I doubt this will be a career adventure, but it’s something fun to learn. Also, if I can’t buy in smaller quantities, can you put together kits with different piece and parts to choose from in same categories? USB ports perhaps those small fuses/ volume control/ knobs/ breadboards I don’t mind spending what you’re asking, but don’t need a whole bunch of extra stuff laying around or stepping on them at night not fun.

Great for camera trigger connectors. (I didn't use them for audio.) I didn't find an available PCB pattern, but after creating one, they work well.

This PJ-320A, along with 3.5mm plug male to RCA female adaptor, helps run a continuity test for the 4-cord (4-pole) headphone with mike a bit easier.

Funcionan bien

These fit nicely into my 3D printed device. They're small but seem to be up to handling repeated insertions of the TRRS plug.
