Great device for music lovers!

I like this speaker overall. The build feels durable, and the sound is very good both outdoors and indoors. My kids especially loved the light effects. The controls are not very intuitive, and I wish there were a mobile app for easier use. The weight is a little heavy, you won’t be able to take it for a long time. Overall, great sound and features!

Amazing Sound Quality

I haven't tried Monster products in a few years and was SO impressed with the BamBox! The sound quality is incredible, especially the bass. The speaker gets super loud and is perfect for playing music outside or around the house. The sound is so much louder and high quality than I expected for a portable speaker! The battery lasts many hours and it is so easy to connect bluetooth to. It's the perfect size and is lightweight, making it so easy to take with you on the go.

Verified Purchase

Bambox rocks

I had to find an all weather Bluetooth speaker in a short amount of time for a birthday party. I wanted something that was weather proof as the forecast didn't look good. I went to Sam's to look at their offerings and found the Monster Bambox. What a great find! It sounded great and got nothing but compliments on the quality of the music. Thanks for a great product.
