Just got the EPH-100. So far I'm very impressed. I didn't expect much but I think they're as good as my Grados.
Obviously they don't stand a chance against my Senns and Hifimans...
But I'm very impressed. The bass is better than I thought it would be. They're good enough for house music and such genres.
Update: The bass might even be overwhelming on other genres than dubstep/ electro.
But what I like the most is the "soundstage", it doesn't feel nearly as compressed as all the cheaper IEM's I've heard.
Mids could be a little bit more forward but they sure a very relaxing.
I also like the extension cable. I haven't tested all the different sizes but it seems like the ones that come on it fits perfectly.
This is not good for my wallet, I might have to get a TOTL IEM now...
This is by far my best buy in audio so far, price/performance wise. Now I actually can't wait to take the train to work on a school project so I can enjoy these guys, that's a first.
