Negative Positive
Title: Loved 'em... 'till they broke!
Review: These had great sound, fit, and balance for running ... until the left ear bud went dead 6 miles into a half-marathon. Something went wrong in the connection between wires and the base of the headphone plug.Admittedly, I didn't try to warranty them; I'm sure I have lost the packaging and receipts.Good for sound, not up for active use.UPDATE: The customer service email was very courteous and sent me a replacement set of J-Buds. I didn't even have to return the broken set! I'm impressed.
