Pros: audio quality
Cons: fragile, flimsy build
Impressed with the sound overall, balanced throughout the frequency range (bass is tight, medium to high frequencies not bad but I still think my Shures are better in the mid to high). That being said, the build is very worrisome - the right shell came apart exposing the tiny speaker and had to be glued. The cord is very flimsy and appears it won't take much of a yank to break the cord. Considering what they cost, I believe a sturdier build could be achieved. There are many China-built IEMs that look to have the same sized housing and can accommodate the same single speaker inside - I bought a pair while in China and for the $7 spent, only the Sunrise's high frequency response was superior.
