And even the cheapest power only USB cables with the cheapest USB power supply provides "standard" 5V power. If your device doesn't accept that, isn't that a problem with your Macbook and not the cable?
The USB standard is fine until the unsuspecting consumer who left the USB C cord to his MacBook Pro 16 goes to a random drug store to pick up a standard “USB C” cable and wonders why their laptop is still going dead after a few hours of heavy use not knowing the cord is incapable of delivering 100W of power.
Or the hypothetical iPhone 16 user goes to the same store because he wants to watch video on his TV and buys a “standard” USB C cable and finds out that the cable doesn’t support video over USB C - which is part of the standard.
Not to mention the unsuspecting tourist who wants to back up the pictures and video from his phone to his computer so he won’t incur roaming charges and finds out the USB C cable he purchased is power only.
Basic cables support 60.
It's unfortunate when cables don't say their Gbps, but that's a different issue.
You're letting perfect be the enemy of good here.
Also I think the ideal endgame is that your Beats Flex headphones don't come with cables at all because of standardization. Look at Apple (and most phone manufacturers) no longer packaging chargers.
