So randomly today I decided to records some voice notes on my phone with my four-ish-year-old Jabra 65Ts and then my BSBs to see the microphone difference (as I'm considering replacing my Jabras, my work buds, soon).
Holy crap - the BSB microphone quality was BAD compared to the Jabra buds - tinny, fading in and out. No way these would be good as my daily work cell buds.
