Excellent portable speaker. Very powerful. Good replacement of bench top multimedia loudspeakers.
Its sound similar to sound of HI-END isodynamic headphones - reach and strong bass, natural, linear mids, no sibilants, dark, rolled off treble.
So if you like sound of Audeze LCD, Hifiman, or similar headphones- that speaker worth of you careful attention.
I'm very happy with my purchase - with that speaker and my laptop I have a party club or cinema just in my backpack
Long battery life
