For the price, the Quedelix 5k is a great way to truly learn what makes your audio great as you play with its glorious 10 or 20-band true PEQ. Even with iOS’ lack of Hi-Res Bluetooth codec support, you should still download the app because iOS and iPad OS don’t have EQ support that works across all your apps. When you consider all of the unit’s other features, I think this device is a no-brainer for those who want to learn about crafting their ideal sound curve or those who already know how to but want a device they can take anywhere and connect to almost any audio source.
