This set of IEM is worth several hundred dollars, not $150.
This is my 5~ 6 months of ownership now. My previous set of IEM was Klipsch Image X4.
Oh wow, man, oh wee wee ... woohoo! wow.
The more I listen to it, the more I like it. You can't find many set of IEMs out there that sound gets better and better as time goes on.
I listen to music but majority of the time I watch videos... anything from TV dramas to movies to music videos to TV-music performance on my iPad 2. The HF-5 is very accurate. It picks up any sound recorded in indoor stage or anything in outdoor. When the two actors/actresses are acting in a small room you can hear that they are actually in a stage in a very large room. This could not be achived using any other earphones I have tried in the past. I also heard someone else making conversation in the background. In outdoor, I can hear birds singing that is a couple of blocks away!! It also makes poorly recorded or compressed sound in music performance sound good. They sound more fresh, airy? It sounds cool, which is the extremely important part. And it does not absorb any sounds unlike the Klipsch S4 which sounds like you put mud in your ear so all that sound is blocked. Or take the sponge and stick them in your ears. It sounded like garbage when watching these TV performances.
This is an amazing work of art, Etymotic HF-5 that is. I'm sure the ER-4 series are just as good if not better.. Something is really wrong they only charge $150 for this thing. What is wrong witht his company?
