When switching from modes the Fairbuds lower the music volume and say a sentence.
I find these sentences to be unnecessarly long, breaking the music listening flow.
here is a suggestion on more concise sentences:
“Noise cancelling on” → “on”
“Noise cancelling off” → “off”
"Ambient sound → “ambient”
or, hold my beer. Go the way Bose went with its quick switch mode.
Noise cancelling - > high tone beep.
Noise cancellation off - > low tone beep.
Ambient sound - > long beep
