I have a love-hate relationship with earbuds: so convenient to carry, but so utterly uncomfortable. I've been searching for years, and tried a *lot* of pairs.
These are, hands down, the most comfortable earbuds I've ever had. They let me spend an hour on a conference call without constantly having to take one or the other of them out to give my ears a rest. They let me hear my music over the noise of the train. They allow me to sleep on the plane.
The little skulls fell off somewhere in my world travels, but the headphones have continued to make those travels better. I picked mine up when they were in the Birchbox bonus shop last year, but I'm debating picking up another couple of spares now that I've seen how they hold up.
