A Bluetooth speaker that sounds really great?

You didn’t mention a budget, but Edifier and Audioengine both make fairly highly-regarded and budget-friendly Bluetooth speakers.  Here are e couple examples but both make higher-priced models if you can spend and/or want more.  I have the Audioengine B2 single Bluetooth speaker and it sounds quite good.  The Edifier uses LDAC and the Audioengine uses aptX HD and not sure if you have a preference.  Hope this helps, and best of luck.

Soix; these options will be great in my man cave. but I need something a little portable and cased better for time outside. I will check these out regardless.

I have the JBL Boombox 3 WiFi Wireless Bluetooth Streaming Portable Speaker and it is outstanding !   When using wifi, you can stream Hi Rez to it.  Battery last forever, and there is nothing louder, and with more bass.  It is a little heavy and big, but, the sound is outstanding.  Note: With WIFI, the JBL app supports the streaming services like Qobuz, so, you can use your playlist in the JBL app and stream HI REZ, otherwise, you just use Bluetooth resolution to stream from any app. 

+1 on JBL Boombox portable wireless blue tooth waterproof, cary it anywhere, yard work, garage, around the fire, down on the dock   Holds charge for days and days.

Get the big one, Boombox 4 is current model.   They go on sale for -100 often.

i have a small one for travel.

Sonos satellites and sub move in and out easily. We do it all the time when bbqing. Plenty of fidelity. Sub adds icing on the cake and easy to grab with one hand. We also have the big JBL disco boom box with the stand and microphones. More for the kids and karaoke and can blast from 50 yards away. Not my cup of tea.
