We've gotten several reports of issues regarding the nitinol rods in our headband assembly failing. We suspect this is due to a combination of factors including the bend radius and the sufficient heating of the rods in the forming process. We are currently working on a revision to the shape as well as working with our vendor to ensure that future rods don't have these reliability issues. As such we are halting production/shipment of any more units until we have resolved this issue with our supplier. If your rods fail, please contact us for replacements. Once we receive the revised rods, all purchasers will have the option to either have rods shipped to them free of charge or to send their headphones to us (at their cost) to have the rods replaced and shipped back (at our cost). This includes ALL current owners.
