On initial listen I am very impressed. This is a really impressive headphone. It is a surprise to find Earsonics producing an analytical sounding phone that retains the amazing mids and lows of the SM3 & putting some sweet icing on the top end.
It is not an SM3+ but rather a new offering all together. The fit is the the usual Westone/Earsonics shape and the build quality appears excellent. It is somewhat heavier than previous offerings and the clear back is very transparent.
The bass is well extended and sounds almost like a good dynamic. The mids are full and very detailed. The highs are extended with a somewhat airy presentation. Soundstage is excellent. As it is rather analytical and bright it may be more fatiguing for long listening periods, but so far I'm really enjoying it.
Is it better than my W4 & SM3? Without hesitation, I think it is technically better. Is it better than my TG334? God no, but what is?
I will post more once my brain has adjusted to the new toy.
