I brought these speaker few days ago, I have used them heavily, for hours, I would say they have done a good job
sound quality is pretty decent, loud enough, to attach with laptop or speakers,
very very easy to pair, just one touch, to pair,
loud enough in a single room
it lacks a bit base, but does the job
the build quality of the speaker is nice and sturdy,
hae multiple options for memory card, and usb drive, aux .
overall a decent product,
