Well, I've used them several times recently (land only, no water) and, quite frankly, I am not impressed. In my opinion, there seems to be little difference between them and the Garrett underwater ones (the "blues"). They sound very similar. Now, I don't know which one is more durable (both are working correctly), but I'm finding it hard to justify double the price. I guess I was expecting them to sound similar to the Garrett land headphones, but they're not even close. The volume control could be nice, and they seem a little louder at full than the blues, but, again, not worth double the price. Not trying to bash Gray Ghost ; I understand they make excellent headphones and they will continue to provide quality products to detectorists. Any thoughts?
