Does the WiiM Sound have better latency and performance than the Audio Pro's for rear surrounds in 5.1?

I've been using the Audio Pro's as wireless rear surrounds mostly successfully. Sometimes there can be a cutout but mostly working okay. Though they are not usable with a gaming setup because the latency is too much even on the lowest setting. You can overcome this with movies since most apps have built in audio sync to delay the picture to the inherit delay the WiiM has in 5.1. Has there been any talk about the performance of these as surrounds? I'm hoping they have lower latency or less drop outs than the Audio Pros.
