Follow up question. Do any of the recommendations have an option to allow voices through? My galaxy buds have an option called "Ambient sound" which basically acts kind of like a hearing aid, piping sound from the mic through to the speaker. It is useful when someone comes and wants to ask a quick question. I know that is somewhat the opposite of "noise cancelling" but I would think they could coexist in some way (i.e. cancel fan noise and hums, but pipe though voice).
