Loud wireless Speaker, clear sound - good bass



Wow wasn’t expecting such good sound quality for the size of the speaker. This goes really loud but you don’t get 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.

Small package BIG Sound!!

Amazing sound for it's size. Really big sound and wonderful clarity! I paired it to my iphone to listen to Bobby Bones podcasts while washing my cars. I sat it in the garage while washing the cars at the end of my driveway. There is zero distortion when you crank up the volume. That means from the end of the driveway I could hear clearly every word that was said. In fact, the volume was so powerful, I realized my neighbor across the street could hear it to. I waved at him and he waved back, so I figured he didn't mind. I then remembered it was waterproof, so I sat it on top of the car I was washing. It has a good range, I can move all around my house with my phone, and it still stays connected. Good sound, waterproof, it's just what I needed.
