Bluetooth is a merely adequate replacement, though. It regularly has dropouts depending on radio interference, and it means another peripheral that needs charging.

I don't know about you, but I regularly - at least 5 times a year - find the battery drained in my Bluetooth peripheral when I wanted to play audio, typically before or during a long trip. I keep wired headphones in my jacket pocket for these times, as a backup. I use three different peripherals often, and I don't track their charge state - the first I know about low battery is when they start giving warnings, usually about 10 minutes before they shut down, leaving me in silence. I don't have the time or patience to be checking their charge statuses constantly, or continually plugging them in to charge up, meaning disconnecting them from their home locations and needing retrieval before use.
