We use these to connect our IEM preamp to the Desk.
So far no one is complaining of drop outs, distortion or crackles, which is ... basically all we want. The signal is clear enough for stage work where you're not exactly after Hi Fi quality just a good feed to your IEMs with the mix you want.
Pros: Cheap, well made, Stereo TRS, coloured for easy reference.
Cons: In hindsight we should have bought longer leads, but it's not a big issue.
It really depends on what you are after, for stage patch leads these are fine for semi pro bands, if you demand top gear and can afford it ... fill yer boots.
These are good wee cables for non name tag snobs.
