I ordered the KZ ED3 from shutian wang on 23 May and the tg-38s (2 pieces) from passerby wei on 12 May, both on Aliexpress. Just picked up the ED3 from the post office, while the tg-38s still haven't arrived (oddly they have a tracking number from the Netherlands). The dispute for the tg-38s is "in progress". (In case you're wondering, I'm in Australia.)
And then it gets stranger. Opened the package containing the ED3 and found a one-Chinese Yuan bill tucked into the cardboard sleeve. Opened the box and found that there was only one stock ear tip (the translucent one with a red core) in place. Looked on the floor to check that the other hadn't fallen off when I took the earphones out of the ziplock bag, but didn't find anything. There were three other pairs of ear tips in the box, but they were all plain black ones. Could the 1 Chinese Yuan (16 US cents) be compensation for the irregular package?
So I've tried the earphones the medium-sized black tips on. My regular earphones these days are the Vsonic GR07 Classic, and the ED3 isn't that much of a downgrade, right out of the box. The initial impression is that the ED3 has a weightier bottom end and a little less top end sparkle. The fit is fairly comfortable, though I wish it had a sliding cinch.
