Cables with mics are an extra 2 points of failure (1 on each side of the control module).
The insulation and wire is physically cut and tiny wires barely larger than a human hair are soldered to a small circuit board. Every time the wire is bent, tugged, coiled up, taken in and out, etc is more wear and tear on the fragile solder joints. All it takes is 1 (out of the 4 solder joints) to come loose, and the whole cable is “bad” and won’t work anymore.
Think of it this way. A rope is made up of tiny individual strands. Which of these 2 would you trust to tow a car up a hilly road, every day for 1 year, without failing?
1. A rope that is continuous and unbroken
2. A rope that has been completely cut in 2, and then individual strands have been glued back together.
And of the above 2 ropes, when it fails, where do you think the rope will break?
Also, sweat and moisture and electronics don’t get along, and the mic control modules are usually not IPX waterproof rated. So moisture and sweat gets into the control module and causes corrosion and shorting.
