Kewl. I may research them
They seem good because of the in-ear headphones, but they still have support, which is probably what I'd like best.
The 19Hz to 20khz (though not as wide ranging as some) doesn't matter because most audio players, etc, only allow a 20hz to 20,000hz limit anyway.
The bass seems good because it has 2 ports on each one for it.
The only thing I can't find about it is the type of cone used to produce the sound...
