I haven’t heard the ZS10 Pros but I have the ZSX and I’m absolutely in love. My previous IEMs were the T2s so I only have that to compare, but they’re definitely more aggressive, better bass and better imaging.
I’d actually agree with the Bad Guy Good Audio’s review of them, except on the point where he says they’re really fatiguing. I get where he’s coming from, and it was like that for me, but you get used to it quite quickly. In my experience - and I’ve been listening to them for 3-4 hours every day for almost a month now - they’re only fatiguing when you max out the volume. The drawback is that you’ll WANT to max out the volume because of the insane amount of detail you get
I’d definitely buy them in an instant. I AM pretty butthurt that I bought them like a day before Blon 03 exploded all over the forums so I’m kinda itching to hear what can be better than this, but TL;DR, they’re comfortable, they sound great and they’re amazing value.
