I know this might be a little too late for a room for changes, but please consider this if possible for Ear 1.
Most of the TWS available in the market don’t have a great quality of mic output as they are far from the mouth and software made for noise cancellation is also not great either.
This is a problem in almost all the TWS earbuds be it premium or mid-range, so if we target this problem and set the bar high for mic output we may get an edge as well 😀
Bonus: Most of us are working from home and that has increased the amount of calls we have to take up.
Your views on this are appreciated!
