Unfortunately, EPH-100's ear sleeves are just too thick to be fully inserted into the ear simulators without tinkering, so measurement data listed below have been acquired sleeveless, fully inserted up to the reference plane. (you can never get to this depth with stock sleeves)
PRO: What a pleasant surprise; Not only EPH-100 delivers a superb sound with virtually no distortion, its frequency range also extends really high.
CON: Left and right channels are slightly mismatched, but it is not big of a deal. Ear sleeves are little too large, even though the IEM itself is very thin. Also, the sub-bass response is just too much with lots of delay. You can say the bass is slow, but at the same time, the delay creates a sound stage of its own.
The one on the bottom shows the same response on the left channel, with the insertion depth at its shallowest. As expected, insertion depth is not much of an issue here, due to the very low acoustic output impedance of the 6mm driver. This is amazing; the driver is actually working independent from the load(ear canal) impedance!
a lot of people on hf seem to dislike the eph100 due to the treble resolution and/or imperfection. I have a growing interest on them since I can source it locally for less than 100 euros, but because I havent sampled one I cant say much.
ReplyDeletewould you care to comment on the treble portion of the eph´s ?
thks
As far as I can tell, this is an IEM for someone who doesn't want any type of "insertion" involved in his/her ear canal. Even if it's barely inserted, EPH-100 should perform as good. Other than that I think you have so many better other options at $200 price range.
