I did a test recently, can only hear up to 14khz, the Mrs has better hearing about 15-16khz
But with ear piece, I can hear it much better, maybe super ear piece , up to 16khz
BTW, the new Apple AirPods Pro sounds very good
Test your ears… and see if you can hear the sounds relative to your age … ★
Touch the Cant hear button when you stop hearing the sound.
An interesting initiative…
Press ‘press can’t hear ‘ when u cannot hear the sound anymore
All must do this test…
Enjoy testing
