Nick, you're not supposed to stretch'em over the point!!
(sour-eye, couldn't resist!!!!)
i like the same ones TC (i think)that is why i buy em from our host (Caboflex #15709 $6). They are so light to wear i fergit to take them off when i'm not using'em. They have slick 'vynil' on the outside (doesn't pick up dirt etc. very easily), and are conical shape that slide pretty easily slides in the ear canal. If i'm climbing, after cutting i might take one side out to listen etc.; that as replacing plug in the ear takes 1 finger lightly, maybe slight push in after.
Very cool, comfortable and light to me. i think the NRR is lower than some other options, but if ya wear 'em more..... anyway they werk for me, with brain bucket too. Can go on after most models, unlike my bugz goggles, that cut down light, and don't fog up. They're very good for scaring lil'innocent kidz too, a real plus!
Sorry about the aural inflection JP, what percentage of cranial danmd-age was that again? How much longer on the (miss)-treatmeants?
