These are amazing! I have been waiting 2 years to get these because thought that 150 bucks was too much. I finally got these from gift cards that I saved and brought them into the field today!People say that it takes time to get used to the tones but I didn't find this to be true. Remember this, these phones sound like a small electric buzzer not a speaker. If you think of it like that you'll be used to it within minutes. The At Pro only has 3 tones. The low still grunts the mid is more comfortable sounding and the high is not as high pitched but just overall smoother sounding. It's almost instant too unlike the softness of the paper cone land phones.These I believe allow easier pinpointing if you use the wiggle technique like I do to locate targets. I'm glad I got these and if you are looking for a very comfortable headset that you can wear for hours that's also water proof like your machine these cannot be beat!These photos were taken the first time I brought these phones into the field. 2 hour hunt in the woods at a local camp.
