I have 50+ miles on my Finis Duo and I still love them. The bone conduction is great and I like not having anything actually in my ears.

No BT; transfers are done as files via the usb charging cable, but that works, and the battery life has been fine, with very little parasitic drain when not in use. No screen, but I keep the music on it simple and I have no problems just going through the list of songs if I really want to listen to something specific.
