I bought two of these thinking I'd just measure the latency and adjust the video player on my Linux desktop to delay the video by the same amount. Installing the software I needed to cast music on Linux was a massive pain and I lost connection on a regular basis, but I got it set up. Used them for just music for awhile and was not thrilled. They sounded great but were just too much trouble to bother with. The latency was around 4 seconds so no way to quickly mute, and when they lost connection I got white noise at full volume in some cases. Then I tried them with video and was shocked to discover that the latency varied. They were completely unsuitable for my intended application.
I planned to sell them but got busy and they just sat on my desk. Then my Internet provider came out with a plan that included free Spotify. I had never had any interest in streaming before but one day I was bored so decided to sign up. Suddenly, I no longer constantly lost connection to one or both speakers and Google Home stopped "losing" my stereo configuration.
I now use them for music for around ten hours a day on average. I hear very little difference no matter where I sit in the room, as long as I'm between the speakers. My teenage son can't get over how "big" they sound. They get plenty loud enough for my 500 cubic meter room unless I really want to crank them up. I paid $85 for the pair. I consider that one of the best deals I have gotten in my life. (Weirdly, one of the boxes was a full pound heavier than the other but the sound and looks are identical to my ears.)
Video sound is now handled by my good quality wireless earbuds that I bought for online meetings.0000000
