Review on KZ AS10 Five Balanced Armature Extra Bass Universal-Fit Earphones In-Ear Headphones (Cyan, No Mic) by Nicole Walker

As a drummer I need headphones with very good isolation that work surprisingly well as earplugs. If you are a musician, especially if you perform, buy them. Just do it. The sound is just wonderful. Excellent balance and clarity across the audio spectrum. A minor downside, in my opinion, is that it has one armature for all 5 speakers, so the bass speaker doesn't have the power potential of a dynamic driver, but still has great bass. Ridiculously cheap for what you get.
