7Hz x Crinacle Zero:2 IEM Review

[Chromatischism]

Does anyone have trouble getting enough volume out of the Zero 2 with an Apple USB-C dongle? Should be louder than the original Zero by the looks of it.

Again, my comment was for hires subscribers who I thought would be the majority here, I was wrong.

Perhaps I'm missing something, but at the low end of "Hi-Res", say 48kHz stereo. That's 2 x channels sampled at 24kHz. So even for a golden-eared young child, that's likely 4kHz of material they physically cannot hear. Is there something beyond the traditional human senses that Hi-Res audio subscriptions offer?

The same thing that cables costing thousands of bucks offer.

Some says that attuniation of dac filter makes the difference. I have nothing to say about this except that I don’t hear the difference.

Some subscriptions may offer different masters for some of the Hi-Res files but they usually don't specify which ones.

By the way- if anyone cant get on with the stock tips- the AZLA SednaEarfit XELASTEC 2 Pairs (Size L)AZLA SednaEarfit XELASTEC work a treat for me on these. Nice and sticky so they stay put. Size required depends on your ears of course.

Just grabbed a couple pairs and will vouch for them as well.
Tried all the stock tips and dozens of other silicone ones from the wife, but XELASTEC is what worked for me.
Thank for the tip!

Tried all the stock tips and dozens of other silicone ones ...

I don't know if I have weird ears, but every silicone tip I tried never sealed and IEMs had little to no bass. I finally went with foam tips (Sonicfoam SF1s) and then the IEM world started to make more sense. I was one of the "don't like, don't need, bought the Zero" crowd. Glad I did, so thanks to @amirm for the review. Got the 7Hz Zero (original), then the Zero 2. I like both but prefer the Zero 2s for general listening (seems more rounded to my ears).

Well, sure. Dog whistle recordings come to mind.

And TS Eliot plays ...

JULIA : He was very clever at repairing clocks; And he had a remarkable sense of hearing -- The only man I ever met who could hear the cry of bats.
PETER : Hear the cry of bats?
JULIA : He could hear the cry of bats.
CELIA : But how do you know he could hear the cry of bats?
JULIA : Because he said so. And I believed him.

Of course this doesn't really come across so well at 44,100 Hz.

Finally got my 1st pair of this Zero 2 owning already 2 pairs of the original 7Hz Zero.

The cable is very flimsy. The chassis fit and finish (mine is the transparent version) is excellent.

I am still tip rolling but I think I found a good one.

The 2s are sounding bassier and darker as designed, but with an unexpected touch more sibilance. Not sure if I prefer it to the original though. We will see.

Lol.

The 7hz zero 2 has standard sized nozzles, the Truthear zero has a larger nozzle.

I sold my Truthear Zero as it was uncomfortable due to the nozzle but i can wear the 7hz Zero 2 for hours with no issues

Must be why the Truthear seem to work better for me, I can push these in more and hold and get better sound.

On the other hand, I've read reports of the Salnotes Zero 2 inserting narrower and falling out more easily.

They absolutely excellent...with better tips. No need for anything more.

Which tips do you use?

You are talking about nozzle /length depth as moulded into the iem shell?, yes they are different as the zero 2 is a shallower fit in the ear canal but it is easy to get a good fit with the right buds of your preference, whether or not the shallower insertion depth leads to a different individual frequency response due to the length/shape of your ear canals I don’t know?.

Does anyone have trouble getting enough volume out of the Zero 2 with an Apple USB-C dongle?

Using the Zero 2s with a Apple dongle (lightning), I find there's way more volume than I would ever want.

Do you have the "reduce loud audio" switched off? It's under settings>sounds and haptics>headphone safety

There is also the issue of making sure you are using a US dongle on a US iPhone. EU dongles have lower volume because of regulatory concern and non-Apple products have lower volume levels unless using certain software.

Just checked and I don't have a headphone safety section in there. I'll have to do some more research—don't need to add to the Salnotes Zero 2 thread for this (should have been in the thread title though, I didn't know this was the Salnotes thread). The Apple dongle is pretty quiet, but gets loud enough at about 75%. Bought it from Amazon a couple of weeks ago.
