DUNU DK-3001 3 x Balanced 1 x Dynamic Hybrid Earphones

Was really looking forward to delving into the world of multiple driver IEM's,alas DUNU 3001 would not afford me the experience.perhaps it is just me,but i just couldn't get these to seal AT ALL with any kind of ear piece.i tried everything from Comply to Swift and none of them would keep the darn things in place.Even if i somehow did,i just can't begin to comprehend the design decisions for the fit.it seems it needs to be on a very particular angle to deliver the entire operational bandwidth of the IEM (5hz to 40Khz)and if it rotates even a milimetre too much,it can go from sharp and brittle,to muffled and "muddy".all in all it was a tremendously frustrating experience.there's no fathomable reason for a headphone to be this difficult to wear properly and will be on my toes and very cautious about future multi driver IEM's
