I have a Fenix headband and I got a couple of Sipik SK68 clones to use with it. However when the flashlights are on the low setting, there is a noticeable high-pitched whine coming from them. It doesn't bother me when I'm holding the flashlights in my hand, but when they are attached to the headband and right next to my ears, it becomes very bad. I even get ringing in my ears after removing the headband, because of the noise from the flashlights. Is there any way to stop this noise, or modify the flashlights somehow to stop it? thanks
