I received ED16 yesterday and left them burning in with pink noise for a couple of hours. I'll compare them to KZ ZSR as they're the only IEM's I've got from KZ. First impression is that ED16 is smaller and less bulky than ZSR (flatter in shape and less width than ZSR) and it seems to adapt better to my ears. The nozzle is back to "normal size" (not oversized like ZSR) so I've had to switch to foam tips because I found the stock tips to be small compared to the big ZSR nozzle. Regarding sound quality, I find them better than ZSR in a couple of aspects: the bass isn't as prominent -or "dark"- as in ZSR which helps emphasize mids and brings a more balanced tuning, and the treble seems to have a bit more definition than ZSR, giving them a bigger, wider and especially more balanced soundstage which I find more appealing than ZSR. There's also a slight increase instrument separation. In fact, after listening & comparing thoroughly ZSR and ED16, I don't want to go back to ZSR, which I now find more muddy and less detailed, with too much emphasis on the low-end. (I'm not saying ZSR are bad, I have enjoyed them so much, but I find ED16 more balanced and enjoyable to listen).do anyone here has ed16 yet?
I wish I could compare them to other KZ IEM's (especially to ES4 due to the positive feedback it's receiving) , but one spanish audiophile reviewer on Youtube says ED16 are the best sounding IEM's from KZ right after ZS10 (not far away from those)
