They constantly disconnect (mechannically) whether from my devices (pedals, outboards) and instruments (bass, guitars). Imagine after getting spare time to make music, you're tracking you guitar in the studio and all of a sudden your signal goes off. Can you imagine a concert?
The Thomman branded extension tube aimed to avoid cable-break right next to the plugs is rigid and makes the shortest patch versions of this cable very annoying to accomodate i.e in a pedalboard.
I bought 6 units: Two 90cms long and four 30cms long. All of the 6 got disconnected at a given moment.
This review is solely based on described problem. Didn't take the time to evaluate signal quality because I decided these cables were unusable for me.
I find this is a pitty because I rather pay premium prize to be sure to be using the product from the moment I get them and trust the quality. Although they look good and they are expensive, and although Thomann's customer service is the best I ever experienced, each product I have to return means a loss of precious time. Some might have enough time. I don't.
