That "revolution" should've come quite some time ago lol..
Only some mfgs support LHDC (Xiaomi, Oppo and their sub-brands like Redmi, Oneplus, Vivo etc) and not all their models do.. even then the support is kinda sketchy..
Big brands like Sony push for LDAC, Samsung for SSC so I don't see LHDC getting much traction. Plus you have LC3/LC3plus HR in the mix now..

Yes, there are already a lot of phones that support LHDC, and I think the future of LHDC is relatively bright

 

[helmutcheese]

Yes, mainly Chinese phones that are/will be banned elsewhere.

I have the issue with it not remembering PEQ. I'm on 1.26. I can't even get a full PEQ entered and have it remember it. I enter it, and it shows on the screen, but if I actually measure them, it appears it's only actually using one of the filters, in this case, it was applying ONLY the 300Hz -3dB filter.

If I navigate away and then back, it will reset the graph in the Fiio app, showing it only has the 300Hz filter saved. And then a bit later... it forgets that one too, and back to totally flat. Any ideas? It's unusable as is, and this is THE reason I bought these, the onboard PEQ.

Is there a step after I have the whole EQ entered and showing, I have to "save" or "apply" the EQ to the device?

Then when I switch between the EQs, it randomly brings up states I had there previously, it seems totally random as to what it is doing. There seems to be some issue possibly as well where it needs to map the PEQ frequency bands to sit with the standard GEQ bands.

Does anyone actually have PEQ fully working and could explain step-by-step what they did? I'll try that, if so. It seems to me though even when the PEQ is apparently entered it's not actually applied to the buds, as I can clearly see in the measurements only one filter was active.

Hey I have it working and haven't had any problems, but I'm sorry to say I don't know why.

It just works for me. The only thing I contend with is the EQ not showing up as it was set when I go into EQ settings, however if I reselect the preset the graph goes from flat to how I left it. No difference in sq when that happens, always starts on the setting I left it.

I have found it will apparently save if I input a simpler EQ, previously I was doing 7 bands but if I reduce to 3 it saves it. I have a feeling the issue may be related to if you have a load of bands close to each other, because of the way it then tries to display the bands on the GEQ, in between the existing pre-set bands (32, 64, 125, 250, 500, 1000, 2000, 4000, 8000, 16000). If you have an EQ that is focused with more bands in a specific range than are in the fixed preset, it then tries to space them out with the preset GEQ bands and appears to lose them.

Like my current 3 band PEQ, I'm doing:

 300 -3 Q0.71
2700 -3 Q2
4750 -3 Q2

And it will save this, I think because it "fits" in between the existing fixed bands it has. Before, maybe there were too many in the wrong places? Bass now goes 32, 125, 250, 300, 500, 1000, 2700, 4750, 8000, 16000.

I'm sort of confused as to how to save these too though, I created the EQ initially while on "USER2" but then went in to switch to "USER1" and it ended up saving my EQ on USER1. At least it's keeping it there now. But it's very unclear to me what it's doing or how to have an EQ of arbitrary complexity stick. This is close enough for now, though.

I'm also getting crackling after a while of listening, which goes away if I disconnect and reconnect.

Are you going into the individual frequencies to change things?

I've used only User 1 from the start and only change the channels provided to me however, I do change each channel. I don't go into them to mess with gain or change channel or anything.

I've only used User 1 as I don't like using EQ (just feel like I'm not good at it). Try a full reset using Helmutcheese' instructions and setting user 1 only (if you're still having issues).

Don't be alarmed if the graph looks flat after opening the app after some time, it doesn't effect the saved EQ.

Also there is no way to save officially. It just does it, would be nice if a little save button was there for assuredly sake. Most people seem to be using Poweramp or some other form of EQ for these due to similar issues to you.

 

[blorg]

Are you going into the individual frequencies to change things?

Yes, I long press each individual frequency to be able to edit the specific frequency, gain and Q. This is really why I bought them, TWS with actual onboard PEQ. PEQ is the going in to change frequency and Q, that's the difference from just using the set bands (which is GEQ).

I know I can use Poweramp (or Wavelet) but the whole appeal of this is PEQ that it will actually store on the TWS.

I suspect the issue is related to my going in to change the actual frequencies, that it has a problem if you change the frequency too much from what was there originally, or have too many in there that diverge from the stock frequency bands, or something. You can see how it replaces some of the existing preset bands with the new frequency, but keeps the other ones in place. I think it may be the algorithm that works out where to put the custom bands can get confused in certain circumstances. It is saving this one (with only 3 bands) now apparently reliably. I'll try another on User2 and see if I can get a whole one in there.

It's just a pity everything Fiio puts out is so buggy on the software side. I have 2x UTWS5 which are also buggy (wake up while in the case and connect to my phone), BTR5, (buggy EQ and battery issues), BTR3, uBTR, BTA30 Pro. As well as FD5, FH3, FH5 (channel imbalance on that one). K5 Pro is probably the best thing I have from them as there's no software for them to muck up. Generally their hardware is very decent but their software is atrocious. Maybe they will get there one day, it's positive at least that they are adding this PEQ function, very few TWS have this level of EQ possible. I have the Sony XM4 and it has EQ but very limited 5 band GEQ, and it's not possible to fix them exactly the way I want them. I think these are probably sounding better than the XM4 now, with this EQ. They have great punch. I think I can probably live with only 3 bands saving, but would be nice to have the full 10 working.

They are sounding very good now with this, I was finding them a bit too boomy and harsh in the upper mids to start- which was expected, as they graph almost identically to the FD5 which I have already. With the EQ though, they have great physical bass impact without the bloat, and the upper mids just smoothed over a bit makes them less fatiguing for me.

Yea it's crazy that for all the talk of having the "latest Qualcomm 51440++++" chipset that the earfun free pro with the airhora chip still handles some things better. Could be the Fiio software, but I'm inclined to think it's a Qualcomm integration thing.

 

[blorg]

It has disappeared again. It seems it can reliably save GEQ set without going in and specifying specific frequency and Q but there is no way to reliably have it save PEQs. Is @FiiO able to duplicate this?

Once you go in and specify specific frequency and Q, some of the time it just doesn't apply these at all. It shows them on the graph, but they aren't actually applied to the EQ. And if you navigate away and back, you'll see they are gone when you come back. For example, this EQ where I just shoved the two custom frequencies up +12dB, it's obviously not doing it (it would be obvious and sound terrible if it did). If I shove up a non-customized frequency like the 1,000, it's immediately audible.

See in the last one, after navigating away and back, it reverts the two customized frequencies to 2000 and 4000, and puts them back to the -3dB I had put on that before.

It was remembering my three custom PEQ filters, I need to figure out now how to get that back in.

This should really just work.

 

[blorg]

The apparent process to save a PEQ (at least 3 bands) reliably:

- start with RESET to wipe everything
- then switch to USER2
- long press each frequency and put in frequency, gain and Q (in my case: 300 -3 Q0.71 / 2700 -3 Q2 / 4750 -3 Q2)
- then click on USER2, to get the EQ menu
- click on USER1
- it will now save the custom PEQ on USER1

This makes no sense, but by following these steps, I can get this 3 band PEQ at least to stick.

It sticks now:

- Switching tabs in Fiio Control
- exiting, force closing Fiio Control and re-entering
- disconnecting the buds entirely and reconnecting them

This cannot be the intended workflow to get a PEQ to stick but maybe it helps others get one in and maybe helps @FiiO get to the bottom of the issue.

The key with it forgetting PEQ, it doesn't seem to forget if you limit yourself to the GEQ and don't long press. It's only if you long press it seems to then be random as to whether it will actually apply what you select or not. It will show it on the graph initially after selection, but not always save it. If it doesn't save it it doesn't seem to actually affect the sound either, so it seems it's only showing on the graph in the app and never going to the buds at all.

For me, and I think many more "audiophile" users, this on-device PEQ is really a key and unique feature that could be a huge selling point. I care about this more than ANC or ambient modes, for the specific use case of these. They are not tuned badly stock, seem to have very good drivers and very good sound with that trademark Fiio punch in the bass and for an IEM really great soundstage, I think these could really be killer if you can just get them to work smoothly.

I agree also i haven't tested it yet but i think whenever you disconnect and reconnect to the device that changed the PEQ random number of times it also resets

I wrote fiio about this not so long ago, I have exactly the same problems.
Also, this "parametric" equalizer has another drawback — the lack of filters. How can a parametric equalizer be without filters? What kind of nonsense is this?
I couldn't stand this insanity and corrected their sound through poweramp eq. You can translate it through a translator.
Link to the preset for poweramp eq.

Thanks for the suggestion, I'll have a look. I'd certainly prefer there was the option of high and low shelf filters, but for this specific IEM I don't feel it's a dealbreaker. Anything like this with a large bass shelf stock I usually EQ just with a single negative peak filter cutting the mid-bass. This gives basically the same result as getting it flat and then adding a bass shelf, but with less filters.

 

[vonBaron]

I'm testing them now vs my ZE3000. They don't switch on and off automatically without app?

I like how they sound most of the time, ergonomic is great but they have almost 0 passive noise canceling.

 

[vonBaron]

Anyone have EQ to U12t?
