Qudelix

I'v been using this app with my qudelix 5k for over 4 months now. I'v used it multiple times daily and have never had an issue with it. I have tried using about 90% of the features and all of them work flawlessly. This app is a LOT better than the one used for FiiO BTR-5. Overall, Qudelix 5x is a quality DAC and this perfectly well made app completes the product 100%.

Probably one of the greatest purchases I have ever made. The companion app is amazing and extremely easy to use with tons of customisation. Although they have removed the ability to toggle absolute volume and volume protection in recent updates. Hope they’ll add it back but other than that its been working perfectly.

So much of this app is just full of usefulness. I swear every week there’s a handy feature I find that I hadn’t seen before. The PEQ is also a fantastic feature that is really easy to use, especially in tandem with other software like AutoEQ and Squig Link, makes this thing a breeze to use.

Simple, tons of settings, full transparency into what’s going on (codecs, sample rates, db). Oh, and this brought new life to my 8 year old IEMs that I had written off as an expensive early mistake. The auto equalizer presets are fantastic. Nothing else like this in such a tiny package. Paired with my iPhone thirteen mini, I’m an ultralight audiophile. A+

Switched to 5k after trying BTR-15. The software here is SO much better than the competition. I wish they could make the UI a little bit nicer and prettier but the sheer amount of options is what we’re here for. I wish FiiO and Qudelix could get together for a collab. FiiO makes the hardware and Qudelix the software. It would be amazing. Oh well! Thanks Qudelix. We’re all eagerly awaiting the 7K or whatever is next.

This has every possible feature, tweak and customization I could ever think of using for the 5k, plus it’s easy to navigate and pretty much glitch-free. Outstanding stuff!

They have been continuously updating the app based on user feedbacks in their forum. I think 5K hardware has so much potential to add more functionality (DSP based) and I look forward to seeing future updates.

I want to better adjust the EQ for my different iems. It would help me best if there was a live 20 band VU meter displayed in low opacity behind the EQ curve. This way I can see exactly where I should make adjustments according to the music I listen to.

Awesome app with a ton of customization. It’s very complex, more so than I know how to use, but there are lots of learn more links available and it’s decently intuitive. Well done and keep up the great work. Excited to see this develop!

Best music app I have ever used. The Q5k has revolutionized music listening. The dac/amp sounds fantastic but the app is game changing. It has more features than my PC eq. Keep it up!!

Please address the issue where the battery graph is unusable on iPadOS. A native iPad UI would also be greatly appreciated but I understand it may be an edge case for a small company. All other controls and the PEQ work as expected; device firmware updates so far have been smooth and error-free.

The app usually works great when it’s on the screen otherwise it’ll cause my iPad to lock up. Some settings won’t apply until I disconnect and reconnect. It causes issues when it’s running in the background and it’s become extremely bad.

They packed a lot of tech into this little box. It sounds amazing and the support is good. My only complaint is lack of labeling on the buttons but they are fairly intuitive.

This app is really great and professional!

Amazing little device but the actual app is very frustrating to use on the iPad since it opens with gigantic black bezels. Please enable modern iPadOS multitasking paradigms so I don’t have to quit what I’m doing and turn my iPad to portrait mode just to use the app.

The Quedelix 5K is an excellent product but the app is terrible (great when it works). App fails to recognize the connected device multiple times which neuters the functionality you get with the app. Even pressing “connect” within the app does nothing.

The sole reason I bought it was to use the autoeq for my airpods max and it has an outdated list that doesn't include all the latest presets for them (I checked the sources git). Please update it or allow us to import autoeqs

Went thru the instructions if having difficulty multiple times. Just won’t connect to apo even though it’s connect to my phone.

Nuff said

connects in phone; not detected in app, even in pairing mode.

I purchased the qudilex 5K from Amazon. I downloaded the qudilex app and from the beginning this has absolutely been a nightmare trying to get the app to recognize the device. At first the app recognized the 5k with no issues. Then the app kept disconnecting from the 5k at random. I initially only had to turn the 5k off and on for the app to reconnect but after several attempts it stopped reconnecting. I did everything that the app suggested. I removed all Bluetooth devices from my settings, reinstalled the app, restarted the phone and the app still will not recognize the 5k Device. I still got the sound, but at a near whispered volume. All of this within 6 hours of using it. The reason I purchased this device is because of the feature rich aspects of the app but the underlying connectivity is completely useless. I have to uninstall it several times. I have to reinstall it several times I have to continue to remove all recognized Bluetooth devices from my phone settings. I have to continuously restart my phone. I should not have to jump through so many hoops just to have the app do what it is supposed to do. It's absolutely ridiculous to have to do all of this. I'm running the latest iOS on my iPhone 13 Pro Max. There's no reason for this to happen. For my budget, This is an expensive piece of equipment, $110 to purchase this and then a brand new update (3.0.0) and it still will not recognize the 5k device. This is absolutely infuriating.
