With the pending release of XP DEUS II firmware V4.0 and the introduction of XP stereo headphones, many detectorists have questions about what’s changed, how stereo audio works, and whether upgrading is worthwhile.
Below, we’ve answered the most common questions to help you understand the new stereo audio system, the benefits of multi-processing, and what the V4 update means for real-world detecting in challenging conditions.
What does “stereo audio” mean on XP metal detecting headphones?
With XP V4.0, stereo audio means the detector can output two independent audio channels at the same time — one to the left ear and one to the right. Each channel can have different reactivity, audio types, discrimination, and targeting behaviour, allowing the detector to effectively operate like two detectors running simultaneously.
This visual comparison highlights the difference between traditional mono audio and XP’s new stereo audio system.
How is stereo sound different from the audio I’m used to when detecting?
Traditional detecting audio is mono, meaning the same sound is sent to both ears. Stereo introduces spatial awareness into the audio. Sounds can be panned left or right, layered, and blended dynamically.
This gives the user more information about target depth, proximity, and behaviour. The brain processes audio faster than visual information, allowing decisions to be made by ear rather than constantly checking the screen.
What’s new in the V4 update?
Firmware V4.0 is a major evolution rather than a minor update. It introduces true multi-processing, allowing two independent detection channels to operate at the same time.
Stereo audio is a key part of this, allowing both channels to be heard and interpreted simultaneously, particularly in challenging ground conditions.
What improvements or features does V4 introduce for XP stereo headphones?
V4 unlocks advanced audio processing designed specifically for stereo headphones. This includes morphing audio and a chorus effect that enhances faint, deep targets.
Stereo panning improves spatial awareness and target separation and is especially useful for users with hearing difficulties.
Can XP stereo headphones be switched between stereo and mono?
Yes. When XP ST headphones are paired and V4 is installed, full stereo and multi-processing features are available. If panning is set to 0, the headphones behave as if in mono.
XP has also introduced the Low Square audio mode, available on both stereo and non-stereo headphones.
Will using stereo headphones increase my detection depth?
Stereo audio does not increase the detector’s physical detection depth. However, it significantly improves how deep targets are heard and interpreted by the user.
Which software version is required to use XP stereo headphones?
You must install XP DEUS II firmware V4.0 or above. Stereo features unlock automatically when compatible headphones are paired.
Can my existing XP Deus II headphones be updated to stereo?
No. True stereo requires new hardware. The stereo headphone range includes upgraded internal processors capable of handling two independent audio streams. Older mono headphones cannot be converted through a software update.
Does using stereo audio affect battery life?
XP designed the stereo system to be highly efficient. Battery life on the detector and remote control is not affected.
Why should customers upgrade to stereo headphones?
Stereo headphones unlock the full potential of firmware V4.0 with richer audio detail, improved target separation and better performance in difficult ground conditions.
