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


Anyway, JUMON PARTY TIME Bluetooth Speaker (5W) is a perfect companion for a DJs Laptop, block parties, and house parties alike. 

JUMON expanded a rich range of Bluetooth Speakers products (3W /5W /10W ) for your option, which can be easy carried for travel, in home, travel, student life, cottage life and  more.
