Using FxSound With Bluetooth Headphones
FxSound works with Bluetooth headphones and speakers the same way it works with wired devices — by processing the audio Windows sends to whichever device is set as default. Bluetooth adds a couple of extra steps worth knowing about.
Connect your Bluetooth device first
Before opening FxSound, pair and connect your Bluetooth headphones or earbuds through Windows Bluetooth settings. FxSound reads the list of available audio devices when it starts, so a device that wasn't connected yet won't appear in its dropdown.
Set the Bluetooth device as default in Windows
Open Windows Sound settings and confirm your Bluetooth headphones are set as the default output device. Some Bluetooth devices register as two separate entries — one for audio playback and one for the microphone/communication profile. Make sure the playback entry is selected as default.
Open or restart FxSound
If FxSound was already running before you connected your headphones, close it completely (including from the system tray) and reopen it. This ensures it picks up the newly connected device. Select your headphones from the device dropdown if they aren't selected automatically.
Adjust presets for Bluetooth audio characteristics
Bluetooth audio codecs can sometimes reduce high-frequency detail compared to wired connections, depending on your headphones and codec support. If audio sounds slightly dull over Bluetooth, FxSound's harmonic restoration feature can help compensate — try the Music preset and listen for whether clarity improves.
What to do if your headphones don't appear
If your Bluetooth headphones don't show up in FxSound's device list even after connecting and restarting the app, check Device Manager to confirm Windows recognizes them as an audio device, not just a Bluetooth peripheral. Reconnecting the device (removing and re-pairing) often resolves cases where Windows only partially recognized it.
A note on latency
Bluetooth audio has inherent latency compared to wired connections, and audio processing software adds a small amount of additional delay. For music and movies this is unnoticeable, but if you're using Bluetooth headphones for fast-paced gaming, a wired connection will generally feel more responsive regardless of which audio enhancer you use.
