One thing to keep in mind when working with angled mini jacks is that the yellow and red wires need to be cut to different lengths in order to fit properly. This can be a bit tricky, but with a bit of patience and practice, you should be able to get it right.

Here are some key characteristics of the angled mini jack:

The second straight mini jack is indeed the most complicated. It requires a bit more finesse than the others.

To start, you need to open the connector and pass the black frame and the black sheath around the cable. Then, you'll need to prepare the wires by cutting the red wire slightly shorter than the yellow one.

Twisting the ground braids together and the cores of each thread is a crucial step. This ensures a secure connection.

Next, you'll need to put the connector and the cable in a 3rd hand, with the ground braid passing through the hole of the frame.

A 3.5mm to 6.35mm adapter is a useful tool for connecting headphones to an amplifier, especially when the amplifier uses a larger 1/4-inch jack.
