The Samsung EHS 70 is/was the single BA of Samsung's line. The EHS-71 uses 100% TWFK. The sound of them (what I get from the few reviews) is harsh, and very light in bass. I think it is because of the white acoustic damper it uses, and the bad stock tips. The first gen UE700, came with the same tips. + The UE700 used green acoustic damper, which is better for taming the mid, high frequencies.
Do you understand all the graphs, used in Rin Choi's measurements or in the reviews of Goldenears? I'm not. But Rin at least provides a summary, which can help. I like written reviews better. You are the one of only few people man can trust in the IEM world.
By the ADDIEM (II), people's opinion confirmed the measurements. And I was a little surprised by your sound rating. That's why I wrote you.
I thought we debunked this:
· Driver Type: Metal balanced armature driver (4.3mm x 3mm rectangular)
The TWFK is not that small. Why not say dual if it is one? The dual dynamic HS330 touts dual speakers. Always seems to be a siren style driver in the 70 and the better driver in the 71.The ED series measurements match up(4.3 X 2.97). Someone crack one open if they are only $50 :)
BTW, interesting to know the new Earsonics is a universal. Most thought it was a custom.
