Just tried this new fitear yesterday. First impression sounds neutral-ish from top to bottom. Somehow I feel it has faster bass decay compared to TG334. Better treble extensions too, even to the C435 (i bet Jaben's Singapore 435 demo unit has issue, sounds worst among 334, 335 and this new fitear).
The vocal is not as polished as 334 though. But take note this is not a finalized product yet. A little discussion with Jaben folks, we have an assumption this could be based on triple driver 333, attributed by its flat sound sig and smaller housing. No official details from Fitear yet.
Personally I kinda like it! Good balanced sound which need a little tweak on vocal clarity and it fits better than TG334 in my ears.
One can only have a dream that this new universal will be packed in Gatling/Gundam housing. Then Fitear will have a winner.
