Twister6 posted a review of the IE 800S over on Head-Fi. As with other twister6’s reviews this one is thorough. Unfortunately, there is no comparison with the original IE 800. I owned an original and loved them but I felt there were other comparable IEMs for significantly less than the $700-$800 price tag.
Pros – very natural tonality, coherent tuning, tiny ceramic shells with 7mm XWB dynamic drivers, modular cable design with 2.5mm, 3.5mm, and 4.4mm terminations.
Cons – cable is not detachable, microphonics wearing cable down (but not up), short nozzle with custom eartips (though, standard Comply supported)
