XP Deus II Firmware V4 Update: Stereo Headphones Only (WSAST / WS6ST / WSAXLST)
XP is preparing to release a new Firmware V4 update, and I want to make this crystal clear before anyone clicks “update”: Firmware V4 is intended exclusively for XP stereo headphone users. If you’re running a mono headphone setup, you’ll want to hold off until the next release (V4.1).
If you’re new to the platform or want the full detector details, here’s the main product page for the detector itself: XP Deus II Metal Detector.
Who Should Update to Firmware V4?
Firmware V4 is for customers using stereo headphones only. You should update only if you already own one of these stereo headphone models:
- WSAST
- WS6ST
- WSAXLST
If you’re shopping for the correct stereo headphone options, this is the exact product listing: XP Deus II Stereo Wireless Headphones (WS6ST / WSAST / WSAXLST) .
Important: Do NOT Update If You Use Mono Headphones
If you’re using any of the older mono headphone models, do not install Firmware V4 at this time. These mono headphone models include:
- WSAII
- WS6
- WSAIIXL
For mono headphone versions, the correct move is simple: stay on your current firmware until XP releases the next update.
When Can Mono Headphone Users Update? (Firmware V4.1)
XP has indicated that a later release, Firmware V4.1, will be the update that opens things up for everyone — including customers using mono headphone versions.
So if you’re on a mono headphone setup, the best plan right now is: wait for V4.1.
My Quick Take (Dealer + Deus II User Advice)
XP is being very intentional with this rollout, and that’s a good thing. Firmware updates can be powerful, but only when applied to the correct hardware. The biggest issue I see is when people update first and ask questions later.
If you’re not 100% sure which headphones you have, check your model name before updating — or just reach out. And if you want to be ready to run V4 the moment it drops, make sure you’re on the correct stereo headset setup: WS6ST / WSAST / WSAXLST Stereo Headphones .
