- KZ AS06 are full-balanced, with a precise “kick” drum.
- KZ ZS10 Pros bass is a dynamic driver. So the kicks sound muddy compared to the AS06.
- KZ AS06 are full clarity, in-your-face, good mids.
- KZ ZS10 Pros sound is V-shaped. Hole at 1khz.
- KZ AS06 don’t extend that high.
- KZ ZS10 Pros have too much high treble (10khz+) at high volume
ZS10 Pros extend down (sub-bass… probably too much for some) and up (10… 15+khz treble too probably), AS06 doesn’t.
Still, I could fall asleep with the ZS10 Pros compared to the AS06. Full-balanced = The audio equivalent of coffee, probably. Especially with this 100hz bump – this fast bass/kick slam reminds me of my T50RPs…
The thing itself:
My ears block with the AS06. I don’t know why. I push these in and “ouch” – with the same tips I use for my ZS10 Pros. Edit: That’s it. Sizes are different. I need comply large tips for ZS10 Pros, and comply medium tips for AS06s.
The ZS10 Pros are smaller and easier to put in your ears. They’re like twice as thin. And they’re also… safer. Because it looks like the little grill mesh is just glued on the AS06 plastic, and fell off one of my earphones already (not a problem with Comply tips: there’s grey foam “inside” too). For the ZS10 Pros, it looks like the tube and the grill are all one part, so it definitely will not move.
Final review, I guess. I still really like both.
TL,DR: ZS10 Pros: Too clear high treble plateau (air!) and smooooth bass and sub-bass extension (maybe too much!), but lacking mids. AS06: Full balanced all-around precision. Good mids. Needs foam tips a bit smaller, needs to be pushed all the way in your ears (smooth fit!), otherwise there’s absolutely nothing under 100hz, and there’a a 8khz-ish treble peak. Excellent when you need high volume (bus, outside, etc).
