I use these cables most commonly with stereo Korg Volca boxes going into a mixing console or audio interface, and any other stereo sound source that only has a mini-jack output, particularly the ones with low output gain.
Cordial use a sleek, sturdy high-quality metal housing on the mini-jack side which is like going to heaven after the legions of flimsy mini-jack connectors you may have already encountered in your lifetime.
XLR side are industry standard Neutrik connectors, colour-coded for your convenience.
Clarity is perfect, no cons from me, great service and delivery from Thomann, highly recommend.
