I bought these to join a miniature mic lead to a standard size one, inside a blimp.
(A bit like Rycotes Conn Box) they are the usual high standard you expect from Neutrik.
Gold plated Pins are readily soldered. A warning though, use a very small tipped iron or you will make a pigs ear of the joints! There are two strain relief bushes supplied, so you get the right size for the cable you are useing. They represent good value for money, as they are a fraction of the cost from other sources. All in all a good buy.
