Using the Air Pro 4 with a Mac
Codec: SBC, not aptX Adaptive or LDAC. The Air Pro 4 support SBC, aptX Adaptive, LDAC and LC3. macOS doesn't support aptX Adaptive or LDAC, and the earbuds don't offer AAC, so on a Mac they play over SBC, the standard Bluetooth codec every pair supports.
Calls sound worse than music. As soon as an app uses the earbuds' microphone (Zoom, FaceTime, a dictation shortcut), Bluetooth switches to hands-free mode, which has much lower audio quality. Pick your Mac's built-in microphone as the input to keep the Air Pro 4 in stereo music mode.
Multipoint. Connects to two devices at once.
Noise control. TuningMac can't switch EarFun's noise cancelling modes yet, so use the button on the earbuds or EarFun's app on your phone. The EQ, volume and output features all work.
What the measurements show
This correction comes from AutoEQ, based on Regan Cipher's measurements of the Air Pro 4. It shows how much to boost or cut at each frequency to bring the earbuds closer to AutoEQ's neutral target:
- Cuts about 2 dB from the upper mids, around 2 kHz.
- Adds about 2 dB to the treble, around 8 kHz.
- Cuts about 2 dB from the top treble, around 16 kHz.
Measured with ANC on.
Fit, ear tips and your own ears all change what you hear, and neutral isn't everyone's favourite sound. Use this as a starting point, then adjust by ear.
Apply it in TuningMac (parametric EQ)

Prefer simple sliders? The 10-band version
No Advanced EQ needed: AutoEQ also gives values for a standard 10-band equalizer, the same bands as TuningMac's main EQ. In the menu bar popover choose Custom, set each slider, and set the preamp to about −2.0 dB.
Values in dB, at 31 Hz to 16 kHz. The parametric version above is more precise.
Questions
Does the EarFun Air Pro 4 use LDAC on a Mac?+
No, SBC. The Air Pro 4 support SBC, aptX Adaptive, LDAC and LC3, but macOS doesn't support aptX Adaptive or LDAC and they don't offer AAC, so a Mac uses SBC, the standard Bluetooth codec.
What are the best EQ settings for the EarFun Air Pro 4?+
AutoEQ's correction, based on Regan Cipher's measurements, cuts about 2 dB around 2 kHz, adds about 2 dB around 8 kHz, cuts about 2 dB around 16 kHz, with a preamp of -4 dB. The exact values are on this page, ready to copy. Treat it as a neutral starting point and adjust to taste.
Why do my EarFun Air Pro 4 sound bad on calls on a Mac?+
When an app uses the earbuds' microphone, Bluetooth switches from stereo music mode to a hands-free call mode with much lower audio quality. To keep music quality during calls, choose your Mac's built-in microphone as the input instead. TuningMac's Input list does this in one click, and its Device Info shows which mode you're in.
Can I control the EarFun Air Pro 4's noise cancelling from a Mac?+
Not yet. TuningMac can't switch EarFun's noise cancelling modes yet, so use the button on the earbuds or EarFun's app on your phone. The EQ, volume and output features all work.
Should I turn off the EQ in EarFun's app?+
For the most accurate result, yes. An equalizer set in EarFun's app is applied inside the earbuds, so it also affects your Mac and would add to this correction. TuningMac's EQ only changes sound from your Mac, so it won't affect your phone.
