For the FX850, are they worth twice the money from the Doppios. I rarely use IEMs anymore cos I still prefer the sound of full size cans, but the FX850s are so handsome and its only 270usd in Japan. The Doppio is only 105usd though.
As for the SZ2000, just curious to hear how low they can go, perhaps will test them out first. I do like the k551s for general music but tend to gravitate back to the hd650. So was thinking of getting something different for gaming, movies & EDM perhaps.
dunno abt zero audio but one aspect of e 850 that makes is sound impressive is it sounds open n big like headphones than iems.
