There isn't really much to say about this Neutrik sockets. The quality is exactly as you would expect it from Neutrik products. I've built a patch panel for my Focusrite Liquid Saffire 56 and everything is working like a charm. Sockets contact is very good, both XLR and jacks fit perfectly so there is no noise or other unwanted clicks or hum if the soldering is done well. Considering their price this are a real bargain.
i used this female connector to build my own multicore. although it is made of plastic, quality is still great. there is no bridge on the back. so i had to solder my own to be able to use the connector for jack and XLR which was quite difficult. but for that price i would by them again and again.
