We use 3.5mm stereo cords in so many different ways, it’s easy to assume that they are all the same.They aren’t.I recently decided to replace all of my 3.5mm connectors and wanted to see if there was a difference in sound quality. There is! This cord replaced another that came with a pair of headphones I stopped using five years ago.I immediately noticed richer sound, and they seem to be built better. The materials are more durable feeling, and the gold plated tips are always a plus.Sometimes small changes can make a big difference. I am enjoying richer sounding audio now, and I am sure this cord is the reason that I am.
