Louder than you think
Rechargeable Li-Ion w/Great Battery Life(12hrs @ mid volume 6 hrs @MAX), Volume to size Ratio is insane, Water resistant and rugged. I am Impressed by these little things, Bought 1 Liked it but dont like MONO sound so I bought another and with the use of a splitter I have very portable and loud Stereo sound. Sound quality is easily the most impressive sound i have heard from a speaker this small (about 1.5 inch) This little thing is a Beast. Looks like a Real deal car audio component got put into a shrinking machine. High Extrusion design yields high output at low power consumption, clear highs and mids, Bass is there but not as much as the highs and mids (What can you expect from from a 1.5 inch speaker?). If using with a smartphone an EQ app can really make these shine if you care enough.
