In all my experience of cable making, I've never come across something like this before. I have made a 3.5mm-3.5mm cable using 20AWG SPC and Neutrik plugs (though the only shop I have access to that sells things like these only sells the China-made 'Neutriks')
However, when I plug in the cable into my iPod and into an amp (I verified this with a speaker setup so the fault lies solely with the cable), the right channel doesn't come through at all.
The weird thing is, both channels DO come through (with perfectly fine sound quality and with the left side's volume level undiminished) if the plug (on the audio-in side, either going into the speakers or into an amp) is is only inserted halfway, which signifies that there isn't anything wrong with the soldering joints, if I'm not wrong.
Would anyone be able to tell me what may be the matter with my cable? ><
