So I've been following this thread, and I fully intend to read it all (currently on page 27) =D
I stumbled onto the EPH-100 during a month-long search of finding the best mid-range headphones suited to my listening needs. I prefer a nice, solid amount of bass, but I'm an amateur audiophile in the sense that I refuse to accept bass if it makes the other frequencies sound ****ty. A more balanced overall presentation that flows within itself is much more enjoyable.
So after researching and researching these things, I could not find anyone who had anything remotely negative about the performance of these buds, and I pulled the trigger last Friday—'Next Day Delivery'—ya feel me!!
They came into the office yesterday morning, and I've been in love with them ever since. Upgrading from my stock iPhone 5 earbuds (which I had to EQ into this V-shape with the low dip at 128), this are a really pleasant surprise. It may be my brain just catching up to the superior quality, but they sound as if they are noticeably improving, even only after seven or so hours of use. They do not NEED to be EQ'd, but, while my phone was in my pocket, divine providence landed me with a really bomb-sounding EQ—a straight line from 32Hz at -2.4db to your highest frequency (circa 16k) at 0 db. Just a straight line. With this EQ, the bass still kicks, but is very warm and really compliments the mids and the high-end; it just sounds exceptionally well-balanced (and, looking at the graph posted for their natural sound, makes a LOT of sense why dipping the bass sounds so good).
Try it out, and gimme some feedback!! Hope it's guuuud!!
These 'phones be the SHIZZZZNIIIIIGHHHHTTTT!!
