Just did a test with a DB meter app ,I know they aren't perfectly accurate but here's a the numbers Test was Bluetooth audio
average 72DB Max 78.9DB
No blue ring like some similar looking models on it when in operation, something allot of people didn't like , just has one small blue led on the side
Mids and highs are definitely where it does a good job , the bass is better then the original Google home (not the mini) and the highs + mids definitely better then the home
(California love) tested @1m away from the speaker
It's about the size of a forearm in length and almost the same thickness of a wrist which is pretty easy to carry around. No it won't replace your TVs speakers but it's a surprisingly good speaker for its small size and price.
