Its been almost three years since my last headphones purchase. I decided this time that I want something a little more portable than what I usually like. I currently have a stock JVC HA-RX700 cans which I use almost daily. Well call me a fanboy but, I have grown very fond to the JVC sound signature. Enough about that... lets get down to business. My price cap is around $50. I have considered these so far: JVC HA-S600 http://www.amazon.com/gp/product/B003ZUXX3S/ref=ox_sc_act_title_2?ie=UTF8&psc=1&smid=ATVPDKIKX0DER Koss PortaPro http://www.amazon.com/Koss-PortaPro-Headphones-with-Case/dp/B00001P4ZH/ref=sr_1_1?s=electronics&ie=UTF8&qid=1365656194&sr=1-1&keywords=kos What do I listen to... almost all genres of music. But one thing is certain... I also listen to alot of very bass heavy music... Techmaster P.E.B., Bass 305, Dynamix II... etc. Other times, I listen to metal and classical from time to time. Any more suggestions ae quite welcomed.
