Remote control to pause, resume, and rewind audiobooks playing from my phone.
- Short press toggles play/pause. Light blinks green.
- Long press rewinds 30 seconds. Light blinks blue.
- It actually sends 3x "previous track" commands, but I have my audiobook player configured to interpret each of those as 10-second rewind.
Why?
I have some otherwise great earbuds that have frusturatingly-unreliable touch controls. This gives me a physical button that reliably performs my most common two tasks.
