Here is another IEM brand most of you probably never heard of, Excellent Sound (EXS) from South Korea. I won't blame you - as I have very little knowledge about this company as well. Here is an interesting dual driver EXS just launched over a month ago, the X20, featuring dual balanced armature drivers from Knowles with impedance of 54ohm and sensitivity of 101dB/mW @ 1kHz. The MSRP is just a little over US$180 and it is pretty much exclusive to S.Korea at the moment. Now you know everything I know about EXS X20.
[UPDATE] EXS is currently looking for oversea dealer. Anyone who is interested can drop me an email.
Oh, check out the picture after the break.
Do Korean always keep the good stuffs to themselves?
