Recently I purchased a pair of Jaybird X3's and in many ways they've been pretty great so far. However, I did notice a pretty substantial audio delay (or lag) being present during certain media playback, especially when playing videos using the YouTube or Instagram app (tested on an iPhone X), and to some extent with other apps such as Netflix. This delay is a lot less present when playing videos in e.g. the Safari browser. I have another pair of wireless headphones, Bose QC35's, which do not have this problem. I've also tried a pair of Apple AirPods, which also do not suffer from this issue. They sync up with video nearly perfectly with a delay that's no more than 10ms. It also seems that both of the latter devices use a syncing strategy that will introduce a slight delay in video playback itself in order to reduce the (experienced) delay, instead of having the audio lag behind.
In the short time I've been playing around with the X3's I've noticed a couple of things:
- When not playing music and unmuting the phone, the keyboard typing 'ticks' are delayed substantially, however;
- During music playback, the typing sound is produced with a much shorter delay, i'd say about 20ms at most.
- When playing videos, e.g. via the YouTube app, the delay is at least 50ms, with sometimes being more than double that.
I've already tried a factory reset as suggested in other threads, which did nothing to improve the situation.
By no means am I an expert on bluetooth audio, but I suspect that the way the X3's handle audio syncing is potentially faulty, whereas a lot of other brands - but definately not all - seem to get it right. Is this something that we can expect to be fixed in an upcoming firmware update? Is it even possible to update the X3's firmware? Is there an ETA for such an update?
I'm pretty torn right at the moment about wether or not I should return them. The X3's are great for music, where the lag really isn't that bothersome. They are, however, not so great for video playback (put mildly), and watching videos during commuting is at least part of the reason I got them. Reading threads started by people who have similar issues with no solution being offered for the past months, doesn't really inspire much confidence either.
If you need any additional info, please let me know.
