Yup I am open to other choices... ;)
My preferences would be in-ear, (so presumably good isolation), Price range: <$150...I listen to varies kinds of music, so the range is important. Balance, with medium soundstage.
I quite like the treble and the details of the UE700 but it was just lacking a tiny bit of bass. Nevertheless I don't like one thats over bassy and too muddy. The X10 is >= then UE700 but I reckon they should put a better cable at that price range. (...refer to the S4 below.)
The 215 I had is quite all-rounded I would say, but I am worried about the durability of the headphone... (I was told I got the bad patch from shure where the connector is flawed. However I have missed the replacement). The wire is quite big as well...
The S4 is another one I like, but the plastic cable tube is coming off from the jack just before it got stolen... The headphone itself is a tiny bit too big to me. and it often feel like it is falling out although it didn't really.
So I would say I can live with a range of headphones but I am looking for a sub-$150, durable balance comfy headphone. I guess there is not much point spending more at this moment as I usually go out with my iPhone.
