XP FX-03 Wired Headphones for Deus and ORX Metal Detectors

The FX-03 headphones are compatible with the XP Deus, Deus II, and ORX metal detectors. All three platforms use a 3.5mm headphone jack that accepts the FX-03's wired connection, and the 30-ohm impedance matches the audio output specifications XP designed for these detectors. Detectorists who own multiple XP models can use one FX-03 headphone across their entire detector collection without needing separate headphones for each machine. The wired connection works with both the original Deus and the newer Deus II platform, so the FX-03 remains compatible across XP's product generations.

The FX-03 is a wired headphone that draws power directly from the detector's headphone jack, so it requires no batteries and never needs charging. Detectorists who hunt in remote areas or run multi-day trips eliminate the battery management and charging infrastructure that wireless headphones demand. The wired connection also removes the pairing steps and wireless dropouts that can occur with Bluetooth or proprietary wireless systems, so the FX-03 delivers audio as soon as you plug the 3.5mm jack into the detector. This makes the FX-03 a reliable backup headphone for detectorists who carry wireless models but want a zero-maintenance alternative when battery access is limited.

The FX-03's neckband design anchors the headphones at the base of the skull where branch contact is less frequent than the top-of-head position that over-ear headphones occupy. Detectorists hunting overgrown homesites, wooded relic sites, or brush-choked parks push through low branches and saplings that catch on protruding headphone frames, and the FX-03's low-profile neckband reduces that snagging. The behind-the-head position also keeps the bulk of the headphone frame away from the forward line of sight, so branches approaching from the front are less likely to hook the headphone structure during entry into dense cover.

The FX-03 includes an inline volume control wheel mounted on the cable. Detectorists can rotate the wheel with one hand to adjust audio level mid-hunt without pausing to navigate the detector's menu system or reach for the control box. This inline control is faster than menu-based volume adjustments when you need to reduce audio during a loud target response or increase volume in windy conditions. The wheel's tactile rotation provides feedback even when wearing gloves, so you can make volume changes without looking at the control or removing your eyes from the ground. The inline volume control eliminates the need to interrupt your hunt to access the detector's settings menu for audio adjustments.

The FX-03 uses a single-sided cable that connects to the detector's headphone jack. Single-sided cable routing keeps one side of the body clear and prevents the cable from crossing the chest or interfering with arm swing during coil sweeps. The cable design provides sufficient length to reach XP detector headphone jacks without creating excess slack that snags on vegetation during field use. To understand how these systems compare to wireless setups, you can read our breakdown on metal detector technologies. The single-sided configuration is a common design choice for field headphones because it reduces cable tangling and simplifies routing during active detecting.

The FX-03's 30-ohm impedance matches the audio output specifications that XP designed for the Deus, Deus II, and ORX headphone jacks, so the headphones deliver clear target tones without distortion or volume loss. Impedance mismatch between headphones and detector can cause weak audio, clipped peaks, or frequency response imbalance, but the FX-03's 30-ohm rating ensures proper electrical loading of the detector's amplifier circuit. Detectorists running high-gain programs or hunting in high-trash environments get consistent audio response across the full volume range without the muddiness or harshness that mismatched impedance introduces.

The FX-03 features a foldable frame that collapses the ear cups inward toward the neckband, reducing the overall footprint to a compact size that fits in a coat pocket or small pack compartment. Detectorists who travel light or carry multiple accessories in a small pack benefit from the FX-03's packability compared to rigid over-ear headphones that require dedicated storage cases. The foldable design also protects the ear cup foam and speaker grilles from crushing when packed alongside other gear. The compact folded configuration makes the FX-03 an excellent choice for detectorists who prioritize portability and minimal storage requirements in their field kit.

The FX-03 will physically connect to any detector with a 3.5mm headphone jack, but the 30-ohm impedance is optimized for XP's audio output specifications. Detectors from other manufacturers may use different impedance targets (8-ohm, 16-ohm, or higher), and connecting the FX-03 to those machines can result in volume mismatch, frequency response shifts, or amplifier loading issues. If you own XP metal detectors and want a universal wired headphone, the FX-03 is the best match, but detectorists running mixed-brand detector collections should verify impedance compatibility before using the FX-03 with non-XP machines.

Consult XP documentation for cleaning guidance on the FX-03 ear cup foam pads. Regular maintenance extends the lifespan of the foam and prevents odor buildup from sweat and field debris accumulated during extended hunts. Replacing worn foam pads is simpler and cheaper than replacing the entire headphone assembly when the cushions degrade from normal field use. To clean the FX-03 ear cup foam pads, gently wipe them down with a damp cloth and mild, soapy water, ensuring no moisture enters the speaker housing. Allow them to air dry completely before your next hunt. Regular maintenance extends the lifespan of the foam..

The FX-03 is covered by XP's manufacturer warranty, which protects against defects in materials and workmanship for the duration specified in XP's warranty policy. Serious Detecting processes warranty claims directly with XP, so defective headphones are repaired or replaced through the authorized dealer network without requiring you to contact XP's international support. The warranty does not cover physical damage from drops, cable cuts, or misuse, but it does cover failures in the volume control mechanism, speaker driver, or structural components under normal field use. Explore our full range of metal detector headphones to compare warranty terms across brands.

Cable replacement on the FX-03 may require professional service through XP's authorized dealer network. Detectorists who hunt in high-abrasion environments can extend cable life by routing the cable inside a jacket or under a shirt to protect it from branch snags and rock contact. If the cable or 3.5mm jack fails, contact Serious Detecting or an authorized XP service center to determine repair options and costs. Proper cable management during field use reduces the risk of damage from cuts, crimps, or connector stress. Protecting the cable from environmental hazards helps ensure long-term reliability of the FX-03 headphone system.
