Lately I've branched into trying Bluetooth. My vehicle didn't come with it, but it has a very good auxiliary plug on the radio/CD player. I found a little rechargeable Bluetooth receiver that I can plug into the aux plug and then play audio books from my phone. I did this because I fear accidentally leaving my phone in the car one day after driving and listening - phones in cars is a major source of vehicle burglaries. I also have a little Bluetooth speaker in the house that I can use with the phone or the tablet. It was getting to where everything paired with that little speaker was greeted with an electronic peep when the speaker found something in range. Then there are the Bluetooth headphones . . . That said, I still have all of the little cables and connectors and adapters earbuds to use with this equipment, and will probably never get rid of them, they're still the most reliable connection, even if they do tether you to devices and snag on the drawer pulls in the kitchen.
