Behringer Powerplay P1

The sound quality is quite good and has enough volume. I have purchased separately USB-C rechargeable Li-ion 9V battery form factor cells with 400-450 mAh capacity and could not drain them in 4 hours. It is not the smallest device, but still quite convenient. The black paint can be easily scratched, but still very sturdy.

Great product, easy to use, no buzzing, but it's important to mention that neither 9V battery nor cable (charger) come with the product, so you will need to buy cable separately if you want to have it powered with a wire.

Super!

It has good sound quality and is inexpensive compared to other systems.

Čakal som viac i keď za tú cenu asi nie. Slabá výstupná úroveň signálu, malý priestor pre batériu, mohol byť trochu ľahší. Funguje, ale netreba čakať zázraky.
