Rated 2 out of 5 by from Very poor design for soldering I have been soldering my own leads and projects for years - not a pro, but a seasoned hobbyist. These jacks have without a doubt the worst design for home soldering. Inside the sheathing is basically just a rod with tiny plastic separators to somehow solder to. Imagine trying to solder 4 tiny wires onto the business end of the jack plug... then make it smaller. I had a quick Google and seems that many 4 pole jacks are made this way. No idea why it doesn't have normal lugs like the stereo ones. Much easier! Anyway, if you can solder the thing it works.

Rated 1 out of 5 by from Poor Design Unlike other Jack Plugs that have loopholes that allow you to thread the cable through and then solder , creating a very good solder point, this product has a tip, 2 rings (identically set up to the front of the jack) with the sleeve acting as the final connection. This make it very difficult to solder up without desoldering the other connections. Found that this make it very easy to short circuit the connection when the plastic insulation melts or the solder bleeds over.
