I have recently gotten the fiio jiezi usbc dongle and when paying with autoeq and my akg k371, I noticed an issue with autoeq-ing it to the diffuse field target.

Whenever I autoeq my akg k371 to the diffuse field -1db tilt target preset, the volume shoots up significantly. This only happens if I start from the akg k371 preset. If I start from the second k371 preset available, called akg k371 (brainwavz earpads), and I autoeq to the same target, the volume is lowered significantly, as expected.

The highest positive gain added in both cases is between 5 and 7 db so the added gain the peq is reporting does not account for the huge volume difference. The autoeq graph also looks fairly similar between the 2 so again I don’t see a gain difference reported that would explain this.

Also, if I autoeq to harman 2018 , in both cases, with the akg k371 and the k371 brainwavz measurements, the volume is lowered, as expected, and it’s very close between them and also similar in volume to the diffuse field result when starting from the brainwavz preset. So this also makes me think the issues is related to the particular combination of akg k371 measurement plus the diffuse field target.

My settings are stock and latest firmware, but I have disabled the inline mic function and set the volume steps to 120 instead of 60.

Anyone experienced similar issues or has the jiezi to try it out and see if it happens to you as well? Thanks

This just happened to me using a new iphone 17 pro max and audio technica m50x bt2! I have been using the lightning model on iphone 14 without issues but when I got the new iphone 17 pro max, as soon as I plugged in my usbc version of the ka11 , updated to latest firmware and which had been working flawlessly on android, luckily I had my headphones off when I hit play because the volume all went to the left earcup and it sounded maxed out…

It happens only when I first plug it in and then don’t change the iphone volume from it’s hardware buttons and only on uac 2.0. Change uac to 1.0 and i constantly hear popping noises. Touch any of the hw volume buttons on the iphone and the issue is fixed until next remove/plug in cycle.

Same iphone 17 pro max , had a similar issue with another non fiio dac and that one got permanently damaged…

You ever find a song that you wanna play over and over non stop until it's burnt into your brain and it just stays in your head for a while ? I just discovered 'I don't wanna be me' by Type O Negative, a band I don't really listen to, but this song is Rockin' ! Only replayed for about 20 times and there's still a lot of daytime left to keep it on repeat and then at night I know it's gonna play in my head over and over and over and... you get the picture 🤘

Had the Wuthering Waves U.C.T.S. OWS for only a few hours and I’m amazed at how good it sounds!

I never played the game and know nothing about it but I got it because I own 2 pills already(red and blue 😁) and I was already fairly happy with them but they get a bit shouty/unclear at high volume with community peq presets and I heard this new one sounded better so wanted to try it but honestly I didn’t know what to expect.

First tried on iphone 17 pro max AAC with some
vocal drum and bass and synthwave and I could immediately tell it was a serious improvement in sound quality. Well defined, balanced, has clear and fairly punchy bass but the mids are very well defined and clear and highs are clear but not overemphasised/sharp or too rolled off… just right. I would almost say it’s comparable in tuning or perceived sound signature to the Sennheiser hd560s post 2022 version…

Switched to Android moto g84 with LHDC lossless 44.1khz 24bit auto bit rate and listening to some oldies but goodies, Gail Ann Dorsey, Huey Lewis, Danzig, Sabbath and I’ve not tried LHDC before but it’s exceeding my expectations, coming from LDAC and even APTX Lossless… I swear, it feels like I can hear a difference in instruments details and even if it’s placebo it just sounds amazing!

Tuning is perfect as is set to standard… not even worth trying peq yet couse I feel almost like I’m listening to a combo of my akg k371 almost in the bass and definitely hd560s in mids and treble.

I’d say that I’m not easily impressed when it comes to headphones and earphones but this one has managed to impress me from the start and that is something only one other headphone has been able to do so far, the OG hd560s post 2022 version so I’d say it’s damn good sounding.

Moondrop should have skipped the pill and gone straight to this open ear hifi madness without having anything to do with whatever game this is and I think OWS would be a lot more popular right now, but I still appreciate the ‘Ultra’ HiFi quality sound Moondrop’s been able to achieve with this OWS. I would recommend it to people looking for audiophile hifi sound out of open ear wireless earphones.

I recently learned about the Aviator 900 ANC when researching Mimi sound personalization enabled over ear headphones and I got one and I am absolutely loving it! The Mimi sound personalization makes a huge difference to music listening, the THX EQ profiles and THX spatial as well and for entertainment in general, all baked into them. They also have ANC and sidetone for utility, and the only weaknesses I can really think of is them not supporting some lossles bt codecs and not working in active mode when wired. Overall I think these hedphones are great for listening to music and entertainment in general and I don't know why they are not more popular tbh ...

Some people praise expensive or particular brands/models of headphones that don't have many or any of the features the aviator has and usually suggest custom EQing your headphones, but really, how amazing can any hardware be if it's sound is not customized to your hearing and how could someone really eq their own headphones correctly without measuring equipment and/or sound engineering knowledge and experience ? Autoeq is good to try but it's hit or miss most of the time and even if the eq might sound good at that time, until you compare with other headphones/tunings and professionally made eq profiles for your particular headphones or your own ears, you won't know how good it really is or what you are missing out on ...

So imo, the aviator 900 ANC having mimi sound personalization, THX EQ profiles, THX spatial sound, ANC and sidetone, while also sounding great(no complaints here) seems like it should be getting a lot more attention.

I got the aurvana ace 3 to try xmems and was blown away by the hearing test based sound personalization! It has made the biggest difference in sound quality and has enhanced my music listening experience more than any eq or dsp! It’s unbelievable how songs that I used to listen to when I was younger, like Dark Tranquility Monochromatic Stains that these days sounded faded, washy, like they had been poorly mastered now sound incredibly good with personalization on. I feel like I’m back in my teens listening to Rammstein’s Sehnsucht album for the first time… absolutely amazing.

Also for context, I have taken several iphone airpods pro 2 hearing tests, recently and they always say hearing aid is not required/recommended so I don’t know why creative’s test does find things to improve but the result is astonishing…

So if you are someone that has the same issues and keeps thinking it’s the hardware or the eq/software, it might just be your ears and you may benefit from this sound personalization feature these buds have to offer.

I just got a seriously pre-loved SXFI usb-c amp, the one discontinued in 2021 or so, and it’s amazing! I have other recent usbc hires dongles but this SXFI one makes my AKG K371 come to life like never before! Playing music on Tidal with volume normalization on my Moto edge 60 neo and it’s booming!

I don’t know why Creative discontinued this product couse in the current hifi hires usbc dongle market, especially since DSP dongles are rare even today or costly and usually don’t offer anything as impactful as sxfi.

I think a new version of this one would be very popular especially since it will work with any player app and with any app level DSP including volume normalization which the SXFI mobile app can’t do unless you use a dsp app that attaches to the Android mixer …

I would 1000% buy a new version of this dongle for smartphones today! Anyone else think this is an awesome sounding device even in 2026 ?

I recently bought an aurvana ace 3 and wanted to try the sxfi app and immediately hit a roadblock on iphone and an annoying issue on Android that made me uninstall the app on all phones since it’s basically unusable…

On iPhone 14 , I simply cannot get it to see any any music files. I have tried using itunes file sharing and drag and drop onto the app icon with aac, m4p mp3 and flac files but the app doesn’t see any of them and I cannot find any local dir where it might store them. Also tried downloading bought music from qobuz straight to the phone but still nothing… I wonder how creative’s testing team tests this app since it’s only supposed to work with local files…

On Android , I have 2 phones both motorola, a g56 and an edge 60 neo and in both of them the volume goes down to 60% every time I go to the now playing screen, the one that has the playback progress bar and the volume and eq buttons. Every time I go to this view or simply click the volume icon without adjusting the volume bar, it drops in volume until about 60%. I have tried everything I could find online but no dice, dolby off, permissions, battery management, etc… it always happens and only on this app… every other music player works fine…

Wondering if others are facing issues like this and if anyone knows a way to get it to see local music files on iphone or fix the volume issue on Android…

Thanks

Hi, I have both the A100 and P100SE and there’s an annoying issue with the Melomania App where if I create a custom EQ for the P100SE it will appear in the EQ list even when the A100 is connected and the P100SE is disconnected. Even worse sometimes it seems the A100 has the previously used P100SE preset selected which obviously won’t sound the same and I have to switch to one of the default ones myself. Is this a known bug ? Thanks

Hi, some phones like the poco x8 pro have ‘Hi-Res & Hi-Res Audio Wireless certification, Dolby Atmos’ mentioned in their specs under Audio Playback and I’d like to know what the non wireless Hi-Res part means.

Does it bypass the Android 16bit 48khz resampling like a DAP does to play up to 24bit 192khz via it’s usb-c port without needing an app like Usb Audio Player to override it and connect directly to a USB Dongle DAC ?

If I connect a headphone that has it’s own DAC and can play audio via usb-c to usb-c cable like the Cambridge Audio Melomania P100SE and play some 24bit 192khz track, will it get downsampled to 16bit 48khz or not ?

If someone knows more about this, please share because I’m considering getting one of these Hi-Res enabled phones to primarily listen to music hi-res music through usb-c, thanks

Hi, I have an issue with my A100. It has happened to me a couple of times now where it seems to shut down during playback or call.

After it shut down during a call previously, I turned off Auto Power Off by setting it to never and didn't have any issues anymore until I re-enabled it as a test.

Steps to reproduce:

- It was already on and Auto Shut Down set to never

- I set it to shut down in 30min

- Started a timer for 30 min and after continuously playing for some time it suddenly shut down.

- When I checked the timer it had 20 seconds left on the clock, likely because it took me a few seconds to find the timer and set it.

Has anyone had this issue ? If it is a bug it would be nice to have it fixed because I love the sound of it and it's my daily driver. Thanks.
