The 5K companion mobile app would be one of the most crucial benefits over the other similar Bluetooth DAC/AMP devices.

In the home screen of the app, you can see and check the operating configuration of 5K at a glance. On each table menu, the users can fine-tune every option for the best sound quality or for the longest battery time.

In addition to GEQ, you can use PEQ to control every little tune over the professional-grade embedded equalizer. 5K is to be probably the world's 1st Bluetooth DAC/AMP supporting embedded PEQ.
