I use bone conduction Bluetooth earphones to listen to podcasts when I run. I notice a high pitched noise, occasionally accompanying the spoken "s" sound. I suppose it's some kind of aliasing and I don't know if it is introduced in the source material, player, Bluetooth or headset. Luckily it's only moderately irritating.

This is just called sibilance [0], it’s most likely in the source material but could be accentuated by a number of downstream factors.

  Thanks for filling in my knowledge of that phenomenon.

This is called sibilance. You're sensitive to high pitched sounds around the 5-6 KHz area. You can either EQ it out or wait it out. Once you're past 40-ish or so the brains own EQ kicks in.

  Thanks for providing a name for that. I'm 30 past 40 so I guess my brains EQ is slow kicking in.

    I think S sounds are high frequency. So are F sounds and it might be harder to distinguish F and S with codecs that don't do high frequencies cleanly.
