Bluetooth earbuds, don't work? (Central Square, Cambridge)

I have charged both up. One of the earbuds had a red LED, the other does not turn on at all. They won't connect to Bluetooth. Please don't ask if I still have them! Once I've given them away, I'll take down the post. Will include small charging cord.

(E.J., in case you end up reading this: your earbuds work just fine. I had these before I accepted your offer. I hadn't gotten around to giving these away yet.)
