imo,435 share a lot more similarities with 846 compared to 335, specially the presentation of upper mid/lower treble region. 846 to my ears sounds like a smaller, but bassier 435.
846's treble does roll off pretty bad(even with the lightest bass filters). The sound above 10k is very muffled(some may consider it as "real")
But I totally agree on the bass of 335, it's no doubt a bassy CIEM with "always-on" mid-upper bass
I heard fit ear is introducing a new product this year. Any info on that?
where did you hear that from?
