Hello, If you really want decent sounding ear buds, but don't want to pay for the Shure SE530's...here's a solution. The top of the line (e500/se530) come with soft, black, pointed foam tips. These will work on everything except the lowest Shure model. And with no music can provide almost perfect isolation....So buy a set ($15 at the absolute most) and then pick up a set of say E4's (180ish now)...You will have found a true isolating headphone for less then half of what Shure wants you to pay. Now, don't get me wrong I can tell the difference between my SE530's and my E4's, but most of us (myself included) don't need the 530's for any reason, and it's kinda like doing heroine.
