"These speakers are quite impressive for the price. I purchased these to be used in a large room for a holiday party and they performed well. Filled the room with pretty good sound, clear with no distortion even turned up high. The battery life seems to be good. I ran them 6 straight hours with no isuues. They were super easy to connect to my Fire Tablet and to pair to each other. The bass is not bad but don't expect them to be as good as higher end wireless speakers like Bose. But for the price, they fit the bill."

Brick! Speaker took an overnight bath in icy/frozen water of drift boat, we got caught in a storm and forgot the speaker was on the floor of the boat…next morning speaker still dripping but blasting tunes. We own two, our toddler has been unable to destroy the 4 yr old speaker. Great for boats/camping/garage, packable for flights, highly recommend.glenn

This speaker is so good I've had it for like 3 years and it's worked well but I was like hey I should write a review after what happened the other day. Basically I left it on the roof of my car and the proceeded to drive 30-45 mins with highway time and it STAYED on my roof and then was rained on all night. And then it turned on and works fine now. What a great speaker.Anonymous

This speaker has worked very well for a little less than 2-1/2 years - from Oct 2023 until Jan 2026. Then the port where the charger goes into the speaker did something. It seems it broke on one side. It just won't plug in any more. Since it's very tiny and hard to see in there, the best we (my husband, techy man) and I can't exactly tell what is happening, it just doesn't work. He tried poking in there, which just make it worse. And it appears these speakers are no longer available at this time. :-(What Customers Talk About
