Purchase date: July 17th. Received on the 20th. Color: White (expected), but BLACK was delivered. I made a mistake, so I repurchased White. Before White arrived, I used the BLACK one to see how the sound quality was for listening to music. Using the app settings in theater mode, the sound quality is quite good. For reference, the purchase price was a bargain at 6990 yen. The price has been changed to 5500 yen.
