I take music with me everywhere I go. The power and quality on this one is amazing. And in this case SIZE MATTERS! Perfect for the beach, trips and film shoots. Couldn't believe the power from such a small device. So glad I got it. I discovered the Cubitt brand a few month ago and they keep amazing me by creating high value low cost devices. They are creating a robust ecosystem of products that are all interconnected. Becoming a loyal fan really fast. Totally recommend this particular device. If you are looking for a waterproof speaker, this is the one to get. You are going to LOVE IT!

Especially the bass. The battery life is pretty good so far, we'll see how long that lasts. I bought this for my teenager so I could hear what kind of music they like and give their eardrums a rest from the headphones. They are happy with this product too!

Very nice sound for a small little device

Maybe 15hrs if you just turn them on and don't use . I noticed after charging them the night before , I went to use them and only have 70 per cent left. I've played them until they shut off and got 2.5 hours of sound. I'm guessing 3.5 hours with 100 per cent charge. I use two speakers for stereo and I must say the dispersion, quality and separation of sound is excellent. But 15 hrs, yeah that's maybe one speaker on low volume.

I love this little speaker. It sounds great considering the price point. I bought it for my shower, but have also found myself bringing it around the house when I am doing little projects or cleaning in different rooms. I've used it for hours at a time and have not had it die or have needed to recharge it. As long as it doesn't go out on me, and I have no reason to believe it will, this was a great purchase and absolutely would bug again.
