Is it difficult to understand what Blue Speaker watts means?
Typically, speakers range from 85-92 db measured at 1 meter with 1 watt applied. Every time you double the wattage you increase the db by 3.
The greater Bluetooth Speaker watts the more shock.
Now for a point of reference for the volume:
10db = normal breathing
60db = normal conversation
110db = shouting in ear, power saw, car horn
120db = rock concert, jet plane at ramp, ambulance siren
