I use this cable for connecting all sorts of mobile devices to the TR input on my mixing board, e.g. an iPad, MP3 player or a digital recorder, or for connecting things to the audio input on my Nord Electro or a Line6 PocketPot. The right combination of plugs saves spaces and fiddling with adapters, which make connections unstable or add risk of bending or breaking something, when connecting to mini phone jacks.
I like that the cable is not to thick, flexible and left/right are clearly marked. The RCA plugs have a rather tight fit. If You need to conenct to standard phone plugs, get two cheap RCA-to-phone plug adapters, which only add about two centimeters to the length of the plugs.
I used several of these cables for years now, thrown them in handbags and mistreated them in various ways but they all still work perfectly, no noise or wonky connections. I suggest getting some of these in different lengths.
