I’ve had one apart and to be fair they are not carelessly made. They’re jacketed in soft silicone under the braid and have thicker than average stranded conductors. You can totally use whatever cables you want, but theirs are built a little better than you’d think and they just feel nice.

Maybe this is a tactile/autism thing for me?

We had a samsung 4k curved tv that has ads on the input menu, and the ad space is filled with a samsung ad if the set has never connected to the internet.

It also harasses you with a pop up about connecting occasionally on startup.

It’s bearable but absurd. We returned it on principle
