Using DT770 my ears detect top end at 16khz & bass extends to the 20hz sine wave.
i got to 12k with this![]()
21 here and i'm a classically trained musician. I think I can hear them all but from 19Khz up the pitches don't sound as high to me or is that how the frequency is meant to sound? I'm using a Plantronics headset by the way.
I heard up to 18KHz. 19K upwards certainly made noise when played through my speakers but it was a lower tone than I heard at 18k
Same headphones here and I couldn't hear anything past 16k too.
