## Questions & Answers

**Q: How is the sound quality of this speaker？**
A: 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.

**Q: 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?**
A: The speaker comes with an Type C to Aux cable

**Q: 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**
A: 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

**Q: 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?**
A: After initial setup speakers  stay paired.
