pro snake Mini Jack / Jack 15563

I bought two of this cables for connecting a eurorack system to an audio interface. In this cable the tip AND the ring of the minijack end are coupled together to the tip of the 1/4" jack. Since one side is TS (mono) and the other is TRS (stereo) the connection should be Tip to Tip and Sleeve to Ring+Sleeve. When using this cable on a modular synth (with mono jack sockets) a shortcut happens between tip and ground, and no audio reaches the interface end.

This tip-ring coupling wasn't specified anywhere, and (for what I've seen so far) is NOT the standard rule for mono cables, since mono jack sockets (1/8" or 1/4") will ground the ring connection.

This main issue aside, the materials seem to be of good quality.

This is the only joint stereo cable around thomann, at least with male mini-jack and male jack ends. I've been using it to transform a left-and-right only output from a mixer into a joint stereo. It means you have the ability to have at least two separate outputs from the master L and R. It is very useful to me :)
The cable seems robust and quite durable, it isn't a PRO cable, but it makes what it says, and for the price that's actually good. The alternative for me would be to solder my own cables, and close to an event I don't have time for that.
Only thing to know, the rubber around it is sort of "rigid" (that's why the 4 stars) you know, you cannot really lay it down without having some curves, but with a bit of effort you manage to lay it down in the way you want.

Thomann have a great cable finding app on their site which helped me to locate this rare cable. I have looked elsewhere but it is really hard to find a cable that will take a stereo mini jack output from a iPad and sum the signal to a mono jack input for your mixing desk line in. Why would anyone want such a cable I hear you ask? Well, in my tribute act band running with backing tracks I sometimes take a small footprint but powerful HK elements system with me running in mono and having the signal summed to mono on one channel is exactly what I need for the gig. Good quality, a decent length and tested with my left, right, centre home grown MP3 just so I know it really does sum the signal. Perfect.

I got this cable as a work around to always having to carry a great number of adapters.
It lasted less than a year, with the connection on the Mini Jack side breaking contact, hissing and finally not passing through any sort of audio signal.
I took it apart to figure out what had happened.
Turns out the connections are as flimsy as they come, with just about 2 strands of thin wire making up the connection. The Mini Jack side of the wire broke off.
Impossible for me to actually repair as the wires are just too thin, it is now useless and a complete waste of money.

Terrible cable, stay away

I'm going to go ahead and state that in spite some people thinking this cable is not worth its value, I do disagree. With the pro snake mini jack, you get what you payed for. It's a basic cable I personally use on my laptop to play some recordings on my monitors, or really to connect my audio interface to my laptop so I can hear what I am playing without the use of headphones. What I am trying to get at is that this cable comes as one with a practical use. You can obviously state that the sound quality you get using it isn't as find as if you had a cable three times more expensive, but that is obvious too. As I mentioned in the beggining of my review, you DO get the ideal cable for the price you put into it. It is solid to carry around on a trip, but not for being used on tour. If your looking for this willing to use it on stage or on professional recording, that I would not recommend. But if you just need it to get going, to play some shows in some pubs here and there, my opinion is that it will be the most suitable.

I needed a bit longer mono cable, mini to normal jack and ordered this. It did not work for me because stereo channels were soldered together. That means if you plug it into mini mono plug, the signal will be grounded. So, no luck.

I am even not sure what what would be the application for this cable. Usually you do not sum left and right just by connecting them together... at least the catalog should clearly state what is connected to what.

Anyway, I am a bit of a handyman, so I got my soldering iron and ventured into modifying the cable. What I needed to do is to unsolder the middle terminal from signal and solder it to the ground. Unfortunately, the mini jack plastic is of bad quality so the insulation melted, and the shaft became wobbly. Scrapped it as unusable.
