I've been using E-A-Rsoft Yellow Neons for over a year now. Around $40 for a hundred pairs delivered from Earjobs http://www.earjobs.com.au/products/e-a-rsoft-yellow-neons-regular-size-uncorded-in-poly-bag-312-1250 I find them very comfortable and effective. Go through a pair or two every week. Can reuse them a few times. Was thinking of getting custom plugs but at these prices.... Just got another 100 pairs which reminded me to put the link up.
