i was surprised myself... Actually I didn't have high hope for it when I took my wallet out. thought Im gonna have a reasonably priced interface for mojo that also deliver music satisfaction as a simple portable solution when it's inconvenient to drag along the combination. I spent one evening comparing the two, now I just sent zishan back for upgrade and put mojo up for sale...
I woundn't say zishan is better. and there are definate differences. but zishan has better synergy with er4s, mk5 and presonus hd7. on the other hand, **** pt15 is the best sounding earphone I ever tried on my smartphone, and I prefer it even to er4s on the mojo>stepdance setup, but with zishan, pt15 sounds exactly like what one would expect for its price.
It is weird, and I realized I might have given up a lot of gears too soon in the past...
