[KB-018] Is a small hum from the X-Force Haptics Kit speakers normal?

Product: X-Force Haptics Kit | Platform: VR (Quest) | Confidence: High

Answer:

The X-Force Haptics Kit audio system is designed to complement gameplay and haptic feedback rather than function as a standalone speaker system. Humming noise in the X-Force Haptics Kit can be caused by the audio source device (such as specific Quest headsets or PC setups) introducing electrical interference due to hardware differences, rather than a defect in the kit itself. To isolate whether background noise is caused by an external audio source or the haptics unit itself, test the kit with the 3.5mm audio cable completely disconnected; if noise persists, the issue is likely internal. The expected high-frequency noise in the X-Force Haptics Kit typically does not impact gameplay as it is masked once game audio begins playing. To further reduce noise, a ground loop isolator should be installed inline between the kit and the external audio source. Radio interference or the reception of radio signals through the X-Force Haptics Kit speakers when connected to a PC via a 3.5mm audio cable is caused by electrical noise from the PC's power supply, which can cause the cable to act as an antenna. This issue can be resolved by using a ground loop isolator on the 3.5mm audio line. High-pitched whining from the X-Force Haptics Kit speakers that occurs specifically when a cable is plugged into the AUX input jack—even if the cable is not connected to an audio source—is a known symptom typically caused by the power supply's performance rather than a hardware defect in the haptics board. While X-Force Haptics Kit power supplies are tested to produce a minimal level of high-frequency noise that is considered an acceptable operating characteristic, if the noise level from the X-Force Haptics Kit is higher than expected, customers can send a video recording for review to determine whether it qualifies for a complimentary replacement power supply. The Upgraded Power Supply for the X-Force Haptics Kit is produced in small batches and limited quantities due to niche demand and high production costs. A disruptive tapping noise from the X-Force Haptics Kit speakers is considered abnormal behavior and indicates a hardware fault, distinguishing it from the low-level humming or high-frequency noise that is considered acceptable for the standard power supply.

A loose or partially inserted 3.5mm audio cable in the X-Force Haptics Kit can cause high-pitched whistling or electrical interference feedback. To minimize background hissing or electrical noise in the X-Force Haptics Kit, ensure that the 3.5mm audio cable is not routed alongside or touching the power brick or power cable. When upgrading the X-Force Haptics Kit power supply to reduce noise, use a 24V DC, 5A adapter from a reputable brand that specifically advertises low ripple or low electrical noise output. Buzzing or distortion in the X-Force Haptics exciters is typically caused by incorrect installation under the front panel, specifically the improper placement of the foam buffer pads. To troubleshoot buzzing or distortion in the haptics kit, Xgaming requires a photo of the internal installation under the front panel to verify the correct placement of foam buffer pads. Xgaming requires confirmation that the noise level from the standard factory power supply for the X-Force haptics kit is outside the normal expected range before offering a higher-quality replacement power supply. The upgraded 24V 5A power supply for the X-Force Haptics Kit is priced at $35.

Xgaming advises that equivalent low-noise 24V power supplies for the X-Force haptics kit, especially those tested with the system, are unlikely to be found on Amazon at the same price as the one offered by Xgaming.
