How is the sound quality of this speaker？

Surprisingly quite loud. I have found you definitely get the best boom when you face the back of it towards a wall or even better a corner. If you have it sitting in the middle of the room it is kind of lacking. My wife has a Bose Soundlink Revolve which does a bit better than the Gravastar, but those Bose are $100 more. Overall its a great speaker and the build of the thing is pretty cool. I have heard of people having the legs snap off, but I handle it like a $200 speaker- I am nice to it haha.

Where is the aux audio port 3.5? I only see usb-c? how do you charge it using the usb-c and plug aux audio cable in at the same time?

The speaker comes with an Type C to Aux cable

What are the db ratings for this device? is the sound okay? would you recommend this to.someome who really enjoys having bass sounding systems? thank

The bass on this thing is entirely bumpin, like if you want a little robot buddy to thump your desk like it worships slaanesh, this is your guy

when you set-up two speakers together using the TWS feature, do you have to do it every time you power off and on or can they stay paired?

After initial setup speakers stay paired.
