This Speakers has big but detailed sound as well as an excellent battery life

On my first test run, I had played it with the light show going the full time, as well as with the above average sound level

One issue I did have and found that other people have, though, is that it will stutter as if it’s buffering about once per song when connected to an Android phone running 6.0 Marshmallow, which admittedly is a few years old now

Usually, I would recommend this option; however, the flat line on the EQ did sound as good as if you elevated each of the three areas (treble, midtone, bass) in some successive pattern

If you pour water on your speaker you don't have to worry as it will bead off the thing.

We use it for background music at home as well as when my daughters are practicing routines with their music.
