GREAT SOUND
This speaker puts out very good Clarity & will go as loud as you could need- ie it will fill your room with sound, Its Not like standing Front row at a Rock Concert but getting that quality of sound will cost a lot more than this portable speaker. Fully charged I tested how long it would last & I got 4 hours at Full Volume- Which was enough for our needs.
