That article is back in 2018 and nothing new really...that was slightly announced after the 4.4mm
I guess it was to compete but seeing many makers are not considering 3.5pro as a primary choice which is understandable as it has no standard unlike 4.4mm
anyways, I don’t care much for 3.5pro. I will care for an M8Pro
What about the M8 did you not like? You seemed pretty thrilled with it.
