Hey, is there a way to measure cables separately from measuring earbuds? I have several pairs of old Iriver buds and the cables are simply beautiful, they are thick and soft, so I am trying to use them with my other buds, but I swear that they make the sound much much worse. How can a cable even do that?
I also look for physical differences when selecting a cable:
- The electrical conductor material makes a difference in sound. To me this is the most important factor.
Copper, silver plated copper, tin plated copper, etc. have different sound.
Just look and try to see if it has copper, silver or tin color. If plated try to scratch a wire and try to see whats behind.
I like pure copper.
- More strands (many thinner wires), makes the wire more flexible.
- A thicker overall wire diameter has less resistance and transports more current.
- I prefer 2 independent ground wires all the way from each earphone to the jack.
A cheaper option is 1 common ground wire from the Y splitter to the jack.
I think maybe separated ground wires could improve channel separation and you can convert them to a balanced jack if you need.
To understand how channel separation is important, try to use a filter in foobar and convert any stereo music to mono and see the difference.
- I also prefer that each of the 4 conductors (Left,Ground,Right,Ground) is individual insulated.
- Insulator is also important and I've read that teflon is good, but I buy what I can.
- My budget is limited so I don't buy very expensive cables, I prefer to use the extra money in better drivers or source.
- Good jacks (connectors) are important, but I don't have much experience here, because they are expensive, I try to select copper.
- Good electrical solder connection is important, the solder spot must be bright/shining after soldering. Sometimes the wires are varnished, best way to remove the varnish is to put a lot of solder in the iron tip and put the wire tip inside the solder for a few seconds. It will melt the varnish. After this don't use that solder for soldering, just trash it.
-> Make sure you respect each driver polarity, positive (+) and negative (-) driver connectors, when you solder the cable.
Phase test (listen to stereo image):
Maybe someone else can add something more.
