How do I solder this jack? There isn't much room for the negative(-) wire. This is for Hifiman headphone.

Put it in a panavise, hit the little step (to the right of the threads in the picture) with flux, tin it , tin the wire, hit it with the flux again and solder on the wire.

Not pretty but works.

What brand jack is that? If you don't mind.

Bought it from eBay. Look for "Upgraded 2.5mm Mono Jack Plug Connector Audio For HD700 Oppo PM-1/2 4Colour".

2.5mm, especially TRRS, are tricky as the contacts are so tiny, especially if you are using larger gauge wire. Your solder joint on the sleeve looks like it may break off, did you get the area warm enough?

Yup, needed some flux for better penetration.

I guess I'll have to resolder it if it breaks off.

Yeah you need to get some flux, the solder will flow much better and provide a nice solid joint... That is not going to last long like that

It was really hard to tin the 2.5mm jack(-) even though I used some flux. It was really easy to tin + side.
