I've never seen bluetooth audio devices that were capable of syncing video and audio in 10 years of using bluetooth audio devices. My most recent tao tronics BT headphones were great for podcasts and audio, but useless for watching video from my Moto X. Have also tested this with Anker portable speakers, Amazon Echo in BT mode, and Creative BT speakers. All are useless for video. I replaced them with a set of $9 Panasonic wired Earbuds that sound just fine and never run out of batteries.
