I've started using these as speakers for my TV, along with a sub woofer to fill out everything under 35Hz. My setup is connected like this:
TV -> DAC & pre-amp > sub woofer -> Beoplay S3 (left) -> Beoplay S3 (right)
The sub woofer relays stereo to the first S3 using the wired input, which sends the right channel to the wired input on the other S3. The sub and the S3s are all preset to a certain volume level, and I control the sound level on the DAC/pre-amp using a remote control. This works very nicely, providing the audio source is continuously playing.
If the audio breaks for 12 seconds or longer, the S3s go into some sort of power saving mode and when the audio starts up again, it takes 3 seconds for the S3s to wake, usually the left first, then the right. This may not sound like a lot, but it's incredibly irritating when a movie is paused, as it means backtracking to hear what was said. Sometimes a movie will start, and a good chunk of the audio is missed because the audio hasn't reached the level to wake them. I can only imagine how these speakers would behave with a movie like "A Quiet Place". In contrast, my sub goes to sleep after about 30 mins of inactivity, as do my studio monitors. Why B&O felt 12 seconds was optimal, I don't know.
Is there anything at all I can do about this?
