Needs work

The device is great, the app needs work. The UI was clearly created by engineers, with no information designer involved. Try figuring out how to set a preset for your PEQ for each headphone. Good luck! Documentation does not provide a coherent answer this basic feature, or is not updated correctly. Unacceptable.

Learning Curve but worth it

The EQ provides amazing results. It can make any IEM sound much better. And in some cases it can make good IEMs sound incredible.

The great app, and even better developers

Super long term support. I can’t believe they updated the app for the new design language. Only app I’ve seen actually do it. NO bugs. Runs well. No crashes. It’s a good app

Wont recognize any Bluetooth devices

I Followed the setup instructions to the t. Once that didn’t work I did the same with the troubleshooting instructions. Would not recognize my headphones or earbuds. App is useless if you can’t connect a device to it.
