These ends are Neutrik and you get the quality that comes with that name.
They sound awesome and wont compromise the sound of anything that you plug into them. They take TRS and XLR inputs and are very useful for a number of applications.
I would highly recommend these and they don't cost a huge amount.
They are easy enough to solder up, they might get a bit fiddly but just take your time so that you don't have them fail on you later on for bad soldering. In doing so you will get to learn some new skills about soldering properly - a skill that is a must in this industry that will save you both time and money when you need to fix equipment.
Pros:
Good sound
Cheap - depending on how many you order
Neutrik quality
Can be used for a number of applications and piece of equipment - always useful to have some of these laying around
Cons:
Do not order these for a patch-bay thinking that these are the right ones. You cannot screw these into a patch-bay as they are designed to be mounting inside of equipment. You need to look elsewhere for the patch-bay ones.
None
Sound good and are of great quality for a great price. Go for it!
