USB headset compatibility with DAC's "USB Host" output

[runecat]

I have a Soundblaster X5 DAC which has a USB Host audio streaming port at the back panel. Documentation for the Soundblaster X5 says that devices that can be connected to the USB Host audio streaming port include "USB headsets."
When shopping for USB headsets, do I need to pay attention to any specs for compatibility with USB host audio. Would a wireless headset work?

Also, what about something like the Soundblaster G3, which is described as "driverless"? If you're wondering why I'd like to plug a DAC into a DAC, reason is that the X5's latency is small but becomes noticeable when playing my digital piano.

It's for USB speakers or headsets, I'd pass on them as there's not a lot of good ones to choose from (and usually the DAC/amp on them is really weak). Wireless won't, the bluetooth on it is for input, like playing songs on your phone to it. Are you using the ASIO driver for it? If you use it's 3.5mm output for headphones there's so many good choices compared to USB ones.
