What’s the sample rate of USB/Optical/Coaxial?

USB supports up to 24-bit 96 KHz, while Optical and Coaxial support up to 24-bit 192 KHz.

My K5 Pro won't turn on with my iPhone 14.

Ensure you are using a USB-C to Lightning OTG cable. For devices that may not output enough power, try using an additional USB splitter cable for power supply.

To power on the device, press and hold the volume button for a longer time.

How to use K5 PRO with PS5?

Plug headset into K5 Pro via 3.5mm splitter. Go to PS5 Settings > Sound > Audio Output, select Output Device > Fosi Audio K5PRO. Adjust mic level to optimal range. Ensure PS5 output/input set to Fosi Audio K5PRO.
