Simply great, great sound quality in a classic format.
The fact of the songs are not well known but suitable for the style gives a retro touch of nostalgia.
Purchase recommended for fans of Miku.

Great headphones, they have different heads for a perfect fit.

I could not go to the concert, and thanks to this edition now I have it in my house!
The extras are great, and the music ... what to say, just Miku
