To start with, this is a mobile device, so the battery should be expensive. This is certainly the case. I had him on the boat for 3 days about 8 hours a day, so the promised 24 battery life is certainly true. The influence of the RGB LED lights is for my feeling nihl. The LEDs are of course not comparable to’ real party lighting’, but my cousin thought it was super fun. The LEDs also seem to start flashing more actively and rhythmically when the music becomes busier. A disadvantage of the speaker is the external damage. The outdoor use of the speaker is particularly encouraged, which is an environment where the speaker can be scratched and damaged. A scratch on the matt black exterior becomes…. You guess it all, WHITE. If you look very closely, it is light grey, but it looks white. This is a missed opportunity. I am very pleased with the sound quality and volume. Speaker used on a campfire with about 25 people. Leave volume at about 75% because otherwise we could not understand each other anymore. Even at maximum power it remains quite pure. It’s a real party speaker, so the bass tones are active, delicious in mixes, dance, house and techno. He is doing a little less well on vocal. This was too clear with Dutch-language music. All in all, very satisfied with the speaker.
