Hey guys, new member to Head-Fi. I've been following these forums for a while now. I got into high-end audio when I required new gaming headphones, I was gonna go for the cheap everyday gaming headset but someone reffered me to Head-Fi. This is when I discovered the existence of headphones like the HD555s and the beyerdynamic DT880s, which I later bought. I was quickly made aware of everything I was missing from my music listening experience since I had never been exposed to high end audio previously. I had absolutely no idea that these "audiophile" headphones could improve my music experience so much. Being a teenager, I move around alot to go to friends places and school and I listen to most of my music on-the-go. So I decided I needed some IEMs. My taste in music is mainly trance and house, but i listen to abit of top40 aswell. I quickly figured out that the klipsch S4s seemed like the right IEMs for me and at just 80$, they were a perfect introduction to the IEM world. However, I felt very unsatisfied with the S4s when they were plugged into my 4G NANO. Compared to the Xonar STX on my PC, it felt like the same songs were lacking fidelity on the Ipod, as if someone crouched down the bitrate. That's when I bought the Cowon J3 and the sound was much improved. So here I am now, looking for an upgrade coming from the S4s. My budget is max 300$. As I said before, my music preferences are bass heavy and I love a good punchy bass. I also like my music with good texture(detail?). I don't like it when the mids are recessed and I can deal with sibilance. So.. any help?
