I have rather miniature ears to go along with my miniature head and miniature everything else. Back in the day, I was rather distraught about highly uncomfortable earbuds and always ended up with the kind of headphones that hook over your ear and cause bouncy troubles while running.
I've been in love with their "form to your ear" foam from the get-go. In fact, I snatch some up whenever I see them on sale. I'm not quite a germaphobe, but something that resides in your ear can only last so long.
I know this is entirely new information (yeah, right), but I go to the gym every day. Do you know the kind of nastiness this brings upon unsuspecting earbuds? (Please say this like Chandler from Friends and it sounds much cooler) Frequent replacement is a requirement in my book.
Recently, I gleefully opened up my most recent shipment of a 1/2 off pair and went to stash them in the waiting area. But wait...what was this? The waiting area was already occupied by three other pairs. Oops!
