I am *finally* upgrading from my Sennheiser cx300ii. Now i know they are a pair of fairly cheap ear-buds, but it is probably my best choice ever made since i've decided to upgrade from my ibud. That said, i've said up enough to further upgrade my ear-buds. I'm currently looking at the Sennheiser IEs and the Klpisch image S4. The reason im comparing the seemingly 'under-powered' S4 with the IEs is that while the S4 has crazy reviews, the IEs doesn't. And when i enquire with my local stereo store, they told me the Klpisch outperforms alot of 'big brands' out there. Anyone with suggestions? P.S I owe a pair of Studios too. I love it alot cause' i didn't pay for it. The sound is nice though imo..
