The R-50 is more lively plus a touch brighter not by much though and has a little bit more detail and a larger sounstage. The EPH-100's bass has a bit more impact and its mids aren't quite as detailed but both have a good 3D presentation. I like both but over all the R-50 is technically better with more micro detail, where I'd give the EPH-100 a 9.1 out of 10 the R-50 would be a 9.3.
