The best test of any speaker is to test and make a purchase decision in the exact location/environment you intend to use it in because of musical acoustics and frequencies being washed out etc. - not just on the store shelf. With that said, I wanted a BT speaker that primarily sounded great in my noisy work environment. This unit performs much better than anyone would think possible. It's amazing and the dynamic range of the music is balance perfectly - not to much base or treble, midrange is exactly were I would set it if using an equalizer. It's physical size is just right! It fits comfortably into my backpack thus allowing me to easily carry from home to work etc. without any 'hassles'. Use it very often in my home garage on weekends and in the pickup when I want portable Blue Tooth! Excellant price/performance ratio.

Very easy to use and setup. My iPhone recognized it immediately. The sound is great for the size of the speaker. Good amount of bass, also. What's really awesome is the mounting kit that comes with it. It will mount just about anywhere. I put it on the handlebars of my mountain bike and couldn't be happier. Rockin' while I roll! Great purchase! Recommend!

Love love love this speaker. I purchased it for the specific purpose of taking it on a canoeing trip since a waterproof speaker was essential for tunes. Of course someone rocked the boat and the speaker went in the water. It floated next to us for a few minutes and all was good with drying it out in the sun after getting it out of the water.

so far so good ,great sound from a small package ,would purchase another if need be

It nice for work and to use it's easy and battery last long
