One of the good things about changing the model to Xperia 1 II is the revival of the earphone jack!
If that happens, you might want to compare. With Streaming Walkman ZX507.
This time, I compared it with headphones. The headphones used are Yamaha's HPH-MP8.
Listen to Goose House's smiling flowers at mora qualitas.
As a result, ZX507 is sent. The sound of ZX507 was smoother and more spacious. But Xperia is also a great fight. This is a good sound that makes you think that you can use a smartphone.
