Review: Great for Split Keyboard Project - The pins take solder easy and the TRRS cord fits snugly. Using this for a split keyboard project and works well.
Review: Great price, worked for project. - 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!

### ⭐⭐⭐⭐⭐ Great price, worked for project.
*by J***. on September 27, 2023*

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.

### ⭐⭐⭐⭐ Good product, but incorrect pinout
*by A***E on November 18, 2025*

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.
