Crazy thing just happened. I went to the mall to meet someone to buy a Galaxy S phone to use as a PMP (has an amazing built-in dac). Then I came across the bose store and went in to A/B my Isurus with the bose in-ears they had, and the bose sounded like total crap in comparison. The Isurus is just so detailed. I walk out very satisfied with my $20 IEMs. Then I got to Marshalls, where my mom asked me to meet her after I was done. Then I found this on the racks next to registers. I promptly threw them in the cart (only 8 bucks over there). Right out of the box I noticed these have crazy bass, but is not as detailed as the Isurus. Still a really good IEM for 8 bucks imo. gonna burn in over night and then see. The best part is that the mic and remote work on this with my iPhone unlike the Isurus' ****ty mic.
