When I go early enough, there is no one there. They let me plug my iPod Shuffle into the sound system via the headphone jack, and enjoy the experience of working out with my playlist going out over the speakers. It's not the same as when I have headphones on; not better, just different, and I like the change. When I work out with other gym customers present, I use my headphones. I agree that with Bluetooth headphones going in the $20-30 range, the use of headphone jack-based devices will go down over time. But there are a lot of those jacks out there in the world, so it will take a long time.
