Are there bluetooth speakers without power saving?

All bluetooth speakers I have researched for a while have power saving which cannot be turned off.
I want bluetooth speakers that don't turn themselves off after a period of inactivity.
Are there such bluetooth speakers?

What would be the point, other than to just drain the battery?


To clarify, as long as there is an active BT audio connection, they should not shut off. If they are, then I would look at your BT transceiver.

Bluetooth speakers will not run on batteries. They will get power from a power outlet. Raspberry Pi Zero W will also not run on batteries while it's connected to bluetooth speakers.

What is an active BT connection? Does a quiet bluetooth audio connection count as an active one?

I read that sony SRS-X1 bluetooth speaker doesn't cut off bluetooth audio connection after a period of inactivity.
It just enters standby mode which it takes about 0.1 second to exit when audio signals arrive.
So, you can lose 0.1 second of audio when audio is played after a period of inactivity.
However, you can prevent it from entering standby mode by playing 20Hz noise continuously.
Speakers cannot react to 20Hz noise, so 20Hz noise is silent.
