I have done two options.
- Google Nest Mini speakers
- VLCThing with Bluetooth speaker
The Google Nest Mini's work well for the most part. You can disable the mic with a physical switch instead of the app. Not sure if that really makes a difference though.
The VLCThing was a really interesting experiment. Once I got the steps down it wasn't to hard to setup, but figuring it out initially was a pain. It actually worked well except for the occasional connectivity issues with Bluetooth. It simply required a raspberry Pi w (computer) and then the speaker. The pi could be replaced with any computer device. The magic sauce is VLC being configured properly and VLCThing on HE. If i was to do it again I would use a wired speaker device to remove the connectivity issue.
