I got 2 of these cheap mp3 headphones with a sd card slot. One charges while the other is in use. The charge is usually good for a few hours. I have a few SD cards with my playlists that I insert on the headphones as desired. They also have Bluetooth capabilities which is a plus. The FM function is mostly useless for me. It's a bit primitive but it works for me. I have no need to pay monthlies and don't care if there's an internet connection. Plus, I don't have to carry additional hardware.
