I've got ribbon tweeters in my Office Speakers and they're incredibly detailed but yes, incredibly directional. In an IEM it doesnt matter - the nozzle only points in the right direction!Planar tweeters are very sweet IMHO. I lke too much trebles rendition from the EMIT tweeters of my Infinty home speakers. The only con about them is: they are quite directional, but in an IEM i believe directionality problem doesn't sussist.
