So I just picked up the JBL Flip Bluetooth speaker to use with my MacBook Pro and iPhone. It got great reviews compared to pricier alternatives from Jawbone and Bose. While it sounds great with music, there is about a 0.3 second lag that makes watching video useless because the mouth is out of sync with the audio. Is this common with ALL Bluetooth speakers when using for video or is there likely an issue with my Bluetooth connection? If its a limitation with all Bluetooth speakers, I'll be going back to the traditional wired route.
