I love using it outdoors in open spaces, but you can still feel it needs its "sister" for stereo sound))) At around 80% volume, it doesn't lose sound volume at a distance of 7-10 meters. If you want a universal sound for home and relaxation, this is your choice. Long-lasting battery, very voluminous natural sound, volume from the mains is even higher than from batteries, backlight, bass boost with several levels, dimensions for such "power" If I wrote the price, then I would not be objective, because for such a price there are very few competitors; that's why they don't exist. use JBL PartyBox 300 more than year |
High-quality sound, beautiful color music in time with the music. Possibility of connection from the cigarette lighter in the car. Within the first hour the strobe light stopped working. use JBL PartyBox 300 less than month |
Already paid off 100 times The battery lasts a long time. Even more powerful from a socket. A speaker that creates a mood))) There is probably one. You just have to be, well, PPC picky. At the lowest volume and at a close distance, noise can be heard (in the background) (barely perceptible) |
