Follow these checks in Audio Fix →When this guide applies
Exact iFi NEO iDSD 2. The sound has unwanted bass/presence correction while a known XBass II mode is enabled. This checks an intentional analog effect rather than diagnosing broken headphones.
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.
