I can't say I've experienced any audio lag with my soundsport wireless. I only watch Youtube through a browser and never their app. Apparently their app is causing issues for some. Games I'm not into.
While watching your videos what source is it (YouTube, Vimeo, or something else) and is through an app or a browser? Either way is it on desktop or mobile? Also can you provide a link so others can test out the same video and see if they experience the same lag? Are your headphones up-to-date with the latest firmware?
Yeah, whether or not they play nice together with audio from various video sources seem to be all over the map. Some have sucess while the next person does not.
I eventually settled on keeping them, despite the issues. I use YouTube in safari.
After 3 months. Conclusion, they really are excellent, and since buying them ive used them every day. I’d advise not rushing to return as there are no perfect solutions out there that tick all of the boxes.
