I decided to upgrade to a Roku Voice Remote Pro, because it's the model with an internal battery and USB-C charging. I thought this made sense because I'm always using the headphone option on my remote, but it kills the batteries real fast, and swapping rechargables from the remote to the charger is a pain.
turns out I got sent the Roku Voice Remote Prop (2nd edition), which is exactly like the original except THEY DROPPED THE HEADPHONE PORT
