I've gotten several pairs of Koss Sparkplugs over the years off of eBay, w/ the etymotic tips. LOVE them, and very reasonably priced. Think I've paid ~$20-30 in the past. Sound is plenty good for me, & with that flanged tip they stay in my ears real good, even with the helmet I'd give you a link, but I just tried searching for them, & not finding anything?? **Here's one I just found. Little more than I used to pay, but I think these are a step up too/cord looks a little nicer... http://cgi.ebay.com/Koss-165622-Kdx100-Earbuds-/230592149169?pt=LH_DefaultDomain_0&hash=item35b05cf6b1#ht_2848wt_1139
