AirPods and Bluetooth audio problems

Fix muffled playback, dropped words, and lag when you dictate with AirPods or other Bluetooth headphones on your Mac.

AirPods and other Bluetooth headphones work with Epilude, but macOS handles Bluetooth audio in ways that can affect playback quality and dictation accuracy. Most of these are macOS Bluetooth limitations, not Epilude itself.

Why music sounds muffled while you dictate

macOS drops Bluetooth headphones to a lower-quality call mode whenever an app uses their microphone, so anything you're listening to can sound muffled or mono while you dictate. This is a system behavior: a Bluetooth headset can either play high-quality stereo audio or act as a microphone, but not both at full quality at once. Playback returns to normal a few seconds after dictation ends.

To keep playback crisp, dictate with a different microphone. Open System Settings → Sound → Input, choose your Mac's built-in microphone (or a wired mic), and keep listening through your AirPods. macOS only downgrades the headphones when they act as both speaker and microphone.

Keep playback at full quality

Set your Mac's built-in mic as the input device and use AirPods for sound only. Your music stays in high quality while you dictate.

Words get dropped or cut off

Bluetooth can disconnect for a fraction of a second, which makes Epilude miss the words you spoke during the gap. Keep your AirPods charged, stay within a few meters of your Mac, and reduce nearby interference from other wireless devices, USB-3 hubs, or crowded Wi-Fi.

If words still drop, reconnect the headphones: open System Settings → Bluetooth, disconnect the device, then connect it again. A fresh connection often clears intermittent audio loss.

Dictation is slow to start

A Bluetooth mic needs a moment to switch into recording mode when you begin, so dictation can be slower to start than with a wired mic, and the first word or two can get clipped. Press your hotkey, pause for a beat, then start speaking. For an instant start, use your Mac's built-in microphone or a wired mic.

Bluetooth also adds a small delay between your voice and when your Mac captures it. The lag is usually harmless, but a wired or built-in mic responds more immediately for fast back-to-back dictation.

Confirm your headphones are the input device

macOS sometimes switches the input device when you connect or disconnect headphones, so Epilude may end up using the wrong microphone. Open System Settings → Sound → Input, select the device you want, then speak and check that the input level indicator moves.

If your AirPods don't appear, pair them first in System Settings → Bluetooth, then return to the Input tab and select them.

Stop AirPods switching to another device

AirPods can hand themselves to your iPhone or iPad mid-session, which pulls the microphone away from your Mac in the middle of a dictation. To keep them on your Mac, open System Settings → Bluetooth, click the info button next to your AirPods, and set Connect to This Mac to When Last Connected to This Mac. macOS then stops routing them elsewhere while you work.

The most reliable setup

For the steadiest dictation, use your Mac's built-in microphone or a wired headset for input. Both avoid the quality drop, the latency, and the connection gaps that come with Bluetooth. AirPods are a good choice when you want to move around, as long as you accept the trade-offs above.

Still having issues?

If audio problems continue across apps, the cause is likely your Bluetooth connection rather than Epilude. Test the same headphones in Voice Memos to confirm, then contact support with your macOS version, headphone model, and whether the issue also happens in Voice Memos.
