I bought AirPod Pro 2’s because I was so stoked over the Hearing feature they announced
However, I could not get the Hearing Test to complete
I repeatedly got the dreaded ‘Unable to Classify’ message no matter how careful I was to take the test in a noiseless environment
I was about to throw in the towel after many attempts when something popped into my head
In the past I had run into issues when recording guitar into my DAW
I kept getting noise on the tracks and I couldn’t figure out why
It turned out that the source of the humming sound was the dimmer switch for my room lighting
A dimmer switch can cause RFI on the electrical wiring which can result in noise on electrical devices such as radios and amplifiers etc.
Remembering this, I turned off the dimmer switch and took the test again (in the dark)
It worked, my test completed on the first pass
Try killing any dimmer switches you have anywhere in your living quarters
and see if this works for you
It’s possible the AirPods were being affected by the dimmer RFI noise, and that was the issue all along
Good luck
I can say without reservation, the AirPods are fantastic for moderate hearing loss
Highly recommended :)
