What makes it a bad cable?
This is the only audio cable I've needed/wanted for a phone in around 5 years. (note, the picture is just an example of the style, not the exact brand I happened to purchase)
For years I refused to even try wireless headphones/earbuds because I was stuck on hurdles like battery life, Bluetooth reliability/range, or the possibility of losing one; but once I actually gave some a try, particularly a good quality set, I honestly couldn't be happier and have come to prefer them over wired headphones quite significantly (specifically for mobile devices). It was genuinely a mental hurdle more than anything. Once I got off my high horse, stopped hating wireless headphones mostly on principle, and realized they actually fit my needs perfectly; I've found the only place I want/need both aux and power connections is at a non-bluetooth stereo.
So now, when I want to charge while playing music at a stereo; this cable is perfect, providing power to the phone and audio to the stereo without some bulky dongle hanging off of your usb c port wearing it out. Since switching to wireless headphones, and buying one of these cables, I have had no desire for anything else.
