I feel a bit the same. I rushed out to upgrade for the better noise cancelling, apparently better mic quality and live translation feature.
All three have been a miss. Noise cancelling is much the same and seems to leak higher pitch noises more. Mic is more or less still bad and the live translation only works in doors in a quiet room.
And I resent the upgrade to 26 and all of the bugs like phantom notifications.
They’re still good ear buds and the noise cancelling is valuable but I shouldn’t have made the upgrade from the 2 pros.
Ahh lastly, it seems the case battery depletes much faster now too.
