I give up.....6 hours of tips rolling, trying to fit A83 into my canals....it sounds good alright ! Exactly like everyone else is saying....probably a brand new pair, so it was lacking a bit of decays, and extensions.....but I boxed it up, and return to Amazon
The Nozzles, and the width of the pairs is my problem....the housing kept on stretching my lobes....and it isn't comfortable at all....hurting a bit....the long nozzles which makes the pairs sit uncomfortably into my canals and not secured. I swapped it to spiral dots, which reduced the length of the nozzles and tips together, it sat in better....but then my lobes hurt
I rarely have fit issue with IEMS...but I found FX750 and IM03, TTPOD t2 fit in more comfortably.
I think Fidue A83 will be a picky/tricky pair for a few people....and I am one of those unlucky one .....sigh....can't join the club.....
