I have two Zulu headsets bought in 2011. By 2017 the plastics became sticky and were breaking down. There was no warranty coverage, but I went ahead and paid 170 each for service to replace the parts that were failing. Now more parts have become that sticky rubber feeling. Multiple e mails and even attempted to phone them to resolve the defects without results. I originally bought the Zulus because they were cheeper then the Bose and I needed two more headsets. My original Bose are 14 years old and still going strong. With the service cost from two years ago I have more money into them then I would have had just going with the Bose. If you have Lightspeed Headsets that are still under warranty and they are the least bit tacky I would recommend sending them in before the warranty expires.
