The box is typical and so is the cable unfortunately. While KZ has come a long way since that awful striped tangly mess of a cable that came with my ZST pro, I would have liked to see the Zar cable or JoyOdio cable come with the flagships. KZ for the most part have 4 basic tips, the White, The classic Starline, foam and those new spirally things. So, let's talk about the build quality, this is a solid design. There is excellent isolation and while they are big, they fit me comfortable. The look is a cool 3D design and I do like that.
The Bass on the AS24 is neutral/ Balanced to boosted just a little, it has good speed in both Sub and Mid and excellent details. It works well with speed metal, Jazz and EDM.
The Midrange is balanced with good body and separation. Vocals are forward and clear as bass bleeds very little.
The Treble is open and airy with rich details and just enough sparkle and extension.
Soundstage: Is phenomenal, offering a wide-open sound with accurate placement and separation that can handle the busiest recordings.
Conclusion: The KZ AS24 is both technically proficient and enjoyable for a large variety of music, it's made well and sounds great.
