It is clear that the sound is not stereo and HIGH END, but clean at 3/4 load, bass strong and the heights come over clean.
The rollers are unfortunately somewhat small and therefore only suitable for slick roads, but the side handle allows comfortable wearing to the site, which can be out in the water, everywhere.
CONCLUSION:
Positives: class BOX good value for a smooth 1, SD card or USB flash drive easily replaceable, 2 wireless microphones, 1 remote control, coupled to 2 nd Box
Negatives: Remote short range, no stereo, super small display.
