any muffled sound as you’d normally get with portable speakers when you raise the volume to almost max capacity. My husband listens to rock / metal music and he gave this speaker a thumbs up. The sound quality is clear and has good bass. Battery lasts long and doesn’t drain quickly so we don’t have to charge this too often for our use. We have been impressed even with the packaging - speaker arrived in a nice box that we have kept for storage when we are not using the speaker. We haven’t tested the water resistance but the mesh protection around the speaker does feel like it’s water resistant. Very nice speaker that produces louder sound than you would expect from a wireless speaker this size. We love it Small but mighty.

This speaker is actually smaller than I expected. It's about the size of a can of soda. But the sound coming out of it is very good. The base is pretty deep, and it's pretty loud too. The metal plate at the top of the speaker vibrates when it plays music. I am worried if it might get damaged if I accidentally touch and put pressure on in while it's playing. Pairing the speaker with my phone is very easy. I have also tried pairing it with my computer, and iPad. They all work fine. And when I turn on bluetooth on the last device it's paired with, it will automatically resume connection. Battery life seems to be very good. I have only charged it fully once since I got the speaker a week ago. I have not needed to charge it again. And I played my music on this speaker a few hours a day. I like the fact that it's water proof and I can answer my phone with it. Now I can answer my phone in the shower, and I don't have to miss important call anymore. I am really happy with this speaker.
