If I learn anything from this hobby, we all have our own preference in the type of sound we like and individual perception differ so much I pretty much accept what I prefer is strictly a personal one.
Once you try fitear, none of us can really listen to Beats or Bose and there isn't really any point in even trying some of the mass (not necessarily cheap) brands.
For me personally, I much prefer the 334 over the 335 but would still like to use the 335 when I feel ambitious.
The truth is that the 334, 335 & 435 are all great ciems and every one of them should satisfy even the most critical listener (but still hoping for something better to be launched soon). When we compare one fitear with another, we will exaggerate the difference not because we want to, but we do hear the big difference.
If others disagree with me, it's what make this world so interesting. While this hobby means a lot to me, it's still only a hobby and I would take it very easy.... Like a grain of salt.
After quite a few hours at Jaben Singapore listening to the MH334s, 335s and the 435s, I've just put in an order for the 335s.
The key factor that led to this decision was actually swapping out the stock cable for Silver Dragons - this made a huge difference for me as the 335s with the stock cable was just a bit too bloated at the low end. The SDs really tightened up the bass and gave the mids and the highs a noticeable difference in detail. This combined with the promise of the SR mod was enough for me to choose the 335s.
In comparison, I loved the treble and soundstage of the 435s, but I really like bass (I'm coming from a non-FP pair of Jh16s) and the 435s just didn't have enough of it. Also, while I could listen to the 335s with the SDs for hours, I got quite fatigued by the 435s after awhile, simply cos of the level of detail in the treble range that they have. They're absolutely fantastic on the right kind of songs, but only if you're listening to a few songs at a time! Hopefully the SR mod for the 335s moves their treble signature in this direction cos thats the main area in which the 435s are better than the 335s for me.
