True Wireless Stereo (TWS) Bluetooth for Speakers

I received four of these yesterday. And for the price it’s really good. Reception for ~15m in a open office landscape.
The voice prompts is really low quality however.

It’s not tws but it would be easy to make a female connector that only pass thru left or right signal.

Unfortunately not able to connect to my other units that use auracast. Similar to this one: https://www.moor-audio.com/products/moerduo-bluetooth-5-3-auracast-audio-transceiver

And this is probably why not every brand have adopted this new bluetooth standard.
