Can I use the XP WS1 or WS3 wireless headphones with DEUS?

[FORUM XP]

No, because the digital link protocol and the frequency band are both different.
DEUS operates on the 2.4 GHz frequency band whereas the WS1 works on 433 MHz.
In fact the essential difference is that the DEUS headphones are not just wireless headphones like the WS1 and WS3, they are also the detector’s brain when the remote control is switched off or absent. They enable most functions to be controlled via their LCD screen and keypad.
