Pros: Excellent sound quality, bass, separation
Cons: Uncomfortable eartips, durability
This is my second pair of EPH-100s. I purchased my first pair in the beginning of 2012 some while after they became a FOTM here on Head-fi. Strangely enough I would have thought that they would have increased in price with the popularity these have, but I got the second pair for $15 less than the first pair I bought. The first pair survived a lot of hours of music at work, but the housings were starting to fall apart. The tips have also become very uncomfortable and I thought it was about overdue to get a second pair.
Listening to the replacement set I was immediately smitten with these all over again. What a bargain for the sound quality on offer! I can't think of any headphone that I've listened to that offers even remotely close to the amount of bang for the buck that these do. In some ways I like them more than the Westone 4s I had previously. The W4s are obviously more detailed and neutral, but these have a certain fun factor and they sound great with modern music and anything electronic. The dynamic drivers also convey a lot of impact which contributes to the fun factor of bass heavy music.
Excellent sound quality, great bass, very good separation and imaging in the mid range, smooth sounding, very good isolation. I was wearing these while sitting close to a couple of 5-axis CNC routers and these isolated the noise very well.
The housings on my first pair fell apart after a year and half's usage. Difficult to get the tips off if you wish to swap them. the ear tips become uncomfortable with extended listening. They also seem to lose some of their flex as they become older. Treble is a bit non descript, but adequate.
