Hello Jim.....as you have heard from Holedigger and Joe, the Sun Ray Gold, and the DetectorPro Gray Ghost are top notch headphones. I have been hunting Indian Wars relics on the Colorado, Kansas, Nebraska and Wyoming plains. While I don't have the sound of the surf to worry about, I often find myself in strong prairie winds, and 90 degree F temperatures.
I have been using the Gray Ghosts since they were first released, and believe that they are solely responsible for me not missing many of my deep finds. I have started using the Sun Ray Gold just this spring, and gotta tell you they are awesome too!
Short of some newer light weight, barely cover your ears, and not block out the noise headpohones, all GOOD headphones are gonna cause sweating, can't really get rid of that in the summer. When it turns colder in the fall, those same headphones help keep the ears toasty.
I don't agree that you are paying just for the warranty however, as the two headphones I mentioned above, are very high quality, and able to amplify and deliver the tones to you even in high noise area. I believe, that is really what you are paying for.
If you have spent the money for the Explorer II, don't comprimise on cheaper, less technical headphones....use the best - with the best!
