Once paired, my experience is that at least with the AirPods, pairing with 'regular' bluetooth devices, while not instant, is pretty quick and painless. I'm not entirely sure if that's because 1) bluetooth technology improved in general, 2) the W1 chip somehow improves 'regular' switching, or 3) or my idea of 'quick and painless' deviates from the norm, but I suspect 1 to be most likely.
The audio system in my car is "Fender".
Serious players know that if you want a Strat or Tele, you get a better instrument from G&L or Suhr than from Fender. Gibson's reputation is in tatters after years of poor quality control and dubious design decisions. A group of Marshall's technical staff left the company to form Blackstar Amps after Marshall went public.
Most of the big musical instrument brands are going the way of Chrysler and Chevrolet - they trade on an old brand image, but there's little of the original DNA left. It's clearly working in the short-term, but I suspect that these brands will fade away with the Baby Boomers that have a nostalgic attachment to them.
How are wireless headphones dealing with something as simple as switching to a different device? I can just replug my wired headphones, but what about wireless? I know AirPods do some of that W1 magic, but that's only if you are dealing with Apple devices. What if I just randomly show up to a friend's house with my wireless headphones and want to listen to music on his ThinkPad?
