Conclusions
You have to shake your head when you see and read about the performance of this $25 IEM. It displays a level of performance with a bit EQ that is world class. Feed it some well recorded music and you are there: the pinnacle of high fidelity sound. I don't care if you don't want to use an IEM. Get one of these (or the original Zero) and get calibrated on what good sound is.As to whether to get the zero or zero:2, I would say that with the above EQ, Zero:2 sounds more to my liking than the original 7Hz Zero. That one though sounds more correct without EQ. Your opinion may vary.
I am happy to recommend the 7Hz x Crinacle Zero:2 IEM.
More bass and less treble peaks / troughs compared to the original neutral-ish Zero - see the frequency response.
Yeah, I buyed. I will EQ it though, need to work out how but I will lol
