Pros Design, durability, comfort, sound quality. These are by far the best pair of earphones I have ever owned. Hands down beat Klipsch S4, Etymotic hf5, AKG. Seems unlikely, but give it a try!
Cons The only cons are the "Jamaica" theme, if that's not something that you associate with - although no one will be able to tell from a distance. If you're super picky, the precision and clarity is slightly better in the hf5's, but it's pretty close.
Summary I literally found these headphones in the street, and while I'm sorry for the loss of the stranger who no longer has them, I am comforted by the fact that I discovered them AND that this poor soul can replace them for about $28. Improbable events for an improbably good sounding and exceptionally constructed pair of headphones.
I highly recommend them, and unfortunately the durability of these earbuds will probably put the company out of business. I have tried the others, and YOU should give these headphones a try.
