The appearance material of Kim Jong Audio is good! The quality is very good, it looks beautiful! The lights are flashing and beautiful! Loud and clear. I like it! The high-end atmosphere of landscape acoustics is not exaggerated at all, low-key and luxurious, especially the battery is really durable. You can charge once a week, and you can enjoy one day in a single play, which is really incomparable to other audio systems!
