Resurrecting an old thread, but I just recently purchased an H502 and H51 and I gotta say THANKS FOR THIS TIP B0wz3r! After wearing my H502 last night for about 30 minutes, I had some pretty deep red dents in my forehead. I loosened it but that didn't help. Could have been a deal breaker for me and Zebralights. I was relieved I wasn't the only one and so thankful to find this tip. It's simple but I wouldn't have thought of it. Adjusting the lamp with one hand now is a bit tight, but way better than wearing an uncomfortable headband.
