Qudelix

Phenomenal app, made by people who love headphone community and use the product themselves. You rarely see this type of end-user customization in non-DIY.

What can I add to all the other reviews ? It’s simply the best blutooth (and more) dac in the world. It also have the absolutely great and necessary Crossfeed fonction !

It rarely seems to want to recognize that it’s on and that I’m even listening to music with it. For some reason the EQ just doesn’t sound right. I tend to keep the EQ off as it sounds better no matter what I try. Hopefully this is fixed.

Wonderful app! 10 band PEQ with pre gain is enough to make this a great app and device compared to it’s competitors. Tons of helpful options to bring out the best of the device and music apps.

Surprised by how good this is. 5x better than the horrendous FiiO app for the BTR5. Only downside is 0 iPad optimization, making it pretty unpleasant to use when not on iPhone.

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

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.

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.

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.

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
