iFi iDSD Diablo 2 — turn off a confirmed inappropriate xMEMS mode. Use the stated exact hardware and connection scope.
Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
Exact iFi iDSD Diablo 2. Conventional non-xMEMS headphones sound distorted and xMEMS mode is positively ON. The exact headphone type is known, Normal power mode is selected and the fixed rear 4.4 mm socket is unused.
Connection scope: USB audio · Optical digital audio · Bluetooth · Analog line / headphone audio. Symptom: Playback sounds distorted.
This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.
If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.
Checks and possible outcomes
Start at scope. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.

Look for: Confirm this exact setup and observation before continuing.
- If Yes, I confirm → Confirm conventional headphones and accept a driver-mode change?
- If No / my setup differs → Continue with source and model support
- If I cannot confirm → More information is required

Confirm conventional headphones and accept a driver-mode change?
xMEMS drive is intended only for the specified transducers. Continue only if these headphones are positively non-xMEMS, front-connected, and you accept pausing and lowering volume before disabling the inappropriate mode. Unknown type must stop.
Look for: Explicit informed acceptance is required before the next action.
- If I accept these effects → Pause and lower volume
- If No / leave this unchanged → Continue with source and model support
- If I cannot confirm → More information is required

Pause and lower volume
Pause source media and lower the headphone dial before changing the driver mode.
Look for: Observe the named indication or available control; stop if absent.

Disable xMEMS
Only for positively identified conventional dynamic/planar headphones, set the external xMEMS mode to OFF. Do not enable it for ordinary balanced headphones.
Look for: Observe the named indication or available control; stop if absent.
