Now I am no audio expert, but I will try and explain why I really do not like these IEM's
Anyway, I received my package containing these a few days ago and they have 50 hours of burn in on them. I have them hooked up to my X-Fi Titanium HD sound card.
I turned on some music, and the first thing I hear is the extremely overpowering bass. I listened to them for over an hour and I could not get used to the sound signature. The bass was just way, WAY too powerful. In fact, It was completely ruining the midrange and treble for me. I was unable to hear parts of guitars that I was hearing with my previous headphones, the Koss Portapro. Just to test it, I went and got my Skullcandy IEM's that I bought at Fry's for $2.99 on clearance, and all the parts of the guitar were a lot more clear. The cymbals sounded much crisper... And I could actually hear them. Yeah. A prefer the $3 skullcandy's over these.
I have been listening to them for hours now and they still do not sound good at all. I tried many varieties of music, and I even tried an amplifier, but they still sound horrible. I cannot even hear the midrange to be able to say if it is good or not. The treble is very faded and weak, and you can barely hear it over the extremely harsh and annoying bass.
So why do people recommend these headphones? I have tried 2 different IEM's all valued less than these in the past few days and they all sound so much better. These are going back to Amazon tomorrow.
