Can meet a variety of music genre. The sound that comes out is a focus on the details. The sound is quite open. Treble with the tone of a line of brushes and vibrant long-fried. A clear sense of youth, but is obviously a little too sharp for the neutral. Bass was tight, hard, tangible good, depending on the setting of the Network News. Feel fit enough to stage a fairly well done.
