Query: Blew Out Speaker in 5 Months

2 Sony V6's were purchased for project studio use. These units were used at normal to just above normal listening / monitoring for artists to track with. In other words, loud enough for the talent to hear tracks to perform to comfortably. The units were never driven to the point of distortion or levels that would be considered excessive. Just at the 5 month mark, one of the headphones had the left driver blow out. The headphones were driven by a Presonus Central Station monitoring system. Obviously others have had a much better experience, just relaying what happened with one of the sets I bought.Update: Now in just under a week after the 1st pair had a speaker blow out, the second pair had the right side ear cushion pop completely off when the studio talent was removing the headphones from his head. So that's 2 sets of the MDR-V6's failing in just 5 months. Based on MY experience, I can not recommend these.
