Yes, pk shells are more comfortable for sleeping. But, I don't want to bust any of the ones that I have - they're up in the $20 CAD region!
Hmmm. I don't have many more than the Pandas I have, as the rest are much more expensive. Looks like I need to buy more, but hopefully there are some cheap variants out there (haven't really looked prior to now). Mine are lasting well, but the cable is starting to have a bit of memory and that's starting to bug me. Kind of thought I was pretty much finished buying buds, but never thought of what happens if my sleepers get busted.
Damn
