I'm just thrilled! The sound: Top! Clear ne right stereo is certainly better, but for the size of the Boombox is already very good and also quite loud. For a normal living room or nursery and ne small party, it is sufficient in any case. But the best are the possibilities: Whether USB stick or via Bluetooth. Super! After trying two minutes my Nokia Lumia played me all music on the part! Geil! Title display from the USB flash drive is also available. Not just song No. 1,2,3! The workmanship is as usual high quality of Sony. Conclusion: For all the technology are interested, buy!
