I really do not like this nor the flames that are likely to precipitate from this post but, for now, I will proceed on good faith.
PEQ did not work at all under the 3.0.1. Nothing under PEQ worked. I'm not going to create a list. Nothing means nothing. All gray.
Under 3.0.3, I was able to enter values in the Spk EQ screen, at one point. I was also able to turn on the Spk EQ, although I cannot right now. All fields worked when I was able to turn the Spk EQ on, except Headroom, pre gain, xfeed. Under Usr EQ, nothing works nor ever has. It's all grayed out. I cannot turn on the Usr EQ and have never been able to.
When the Spk EQ was working, I could not save them to a custom preset. They are still in there from yesterday, though. I can see them right now, although grayed out.
OK, on to Auto EQ Preset. This screen lets me type my headphone make/model. The search works but touching the result does not load the Spk EQ, or change any setting. There is a quick flash of a white box that reads, "FETCHING" and then it returns. There are no buttons or anything for me to try. Going back to Usr EQ shows a default chart while Spk EQ shows the chart I entered yesterday, when I was able to turn on the EQ for a few minutes.
I've done dozens of System Resets, Reset All Settings (a few times), and power cycled my phone a half dozen times. I also tried the app from a different phone (my phone is Android 13. the other phone is Android 14). Same result. Q5K batt is at 90%. I've made sure headphones are plugged into the Q5K with music playing the entire time, so I can know it is connected via BT.
When searching for a solution, I found several people with the same problem on Reddit (r/headphones). Unfortunately, none with resolution. A DM to one of the posters revealed he never figured his out.
So, I went to the Qudelix website. I posted there, although I should not have. There is a suggestion to come here, so I did.
OK, let's talk about feature regression. None of my confluence filters work. That is no longer how it's designed. This isn't a feature addition; this is a feature change. OK, I might be able to tolerate that, although I am auser who is not served well by it. I would have preferred they left the old config and add the new approach as an option but I get what they are doing.
Previously to yesterday, I hadn't tried the Chrome extension but I was able to install that and it worked well, for the most part. Some of fields showed "N/A", (but are correctly populated in the app), but none of the fields which wouldn't display were needed. I think this was probably working correctly.
Squig.link is not OK. I can probably find a Windows system with a browser that it works on but I only have W10, right now. I cannot cite the version of Chrome without the laptop and my wife is using it. Almost all fields remain grayed out. Two of my headphones are in the Squig.link supported list, three are not. My IEMs are not. The supported list is really short. Generally speaking, Squig.link looks like it's going to be a nice thing, one day. I respect the developers and what they are trying to do.
Oddly, surfing to Squig.link with Firefox/linux works well. I suspect properly. It even has the Harman 2018 house curve, which is the closest to my preference. Of course, this isn't needed with the new Q5K config model but the site looks interesting.
Anyway, it looks like I could get the Qudelix app to do what I want without using Squig. I create confluence filtes every day as part of my job, although not in the audio spectrum.
It's not so much that something is broken. It's more that very little works.
I will leave this here. If anyone knows of a way to get v2.x firmware onto the Q5K, I would be extremely grateful. Please DM me if this thread turns hostile. Thank you for your time.
