Query: The sound of frustration

Truly the most aggravating headphones I have ever owned. The sound is really impeccable, but only for the very short time one is able to keep them inserted in the ears. They will fall out - in my experience with any of the three sizes of ear bud - at the slightest provocation. A light breeze will cause them to unseal, ruining the depth of sound immediately. Turning your head or even the weight of the cord, which is substantial with the utterly necessary extension, will pull them completely out of your ear canal in a matter of minutes. They are useless for running (I even tried taping them to my ears, which, despite not working, is stylistically ridiculous). The first headphones I have actually HATED. Only rate above 1 star because, for the briefest of moments, they also happen to produce the best sound of any in-ear style headphones I have owned.
