Very good for searching for coins.Works goodLove them. Very comfortable.I have two of these, that are used for different metal detectors. I have had one pair for over a year without any problems or complaints. The individual volume control for each ear cuff is a great feature to have. I can wear these for hours on end without discomfort while detecting. The sound is crisp and clear, just what you need when listening for tones. I liked them so much that I ordered another for my new detector. Outstanding performance and a great product. Well worth the price! Thanks First Texas!These work well for what they are for...blocking environmental sound, providing a good sound to your ears from the detector, individual volume controls.What I don't like is that they are bulky, hot, and sweaty, and if your eyeglasses are behind your ears, your ears will hurt when you are done! Also, if you use a pinpointer (I recommend the Garrett ProPointer), you will be taking these off and puting them back on constantly.So...they work well, but I wish there was a better solution. I have ordered an adaptor so my iPod headphones will fit...only problem is, I won't have any volume control (no, your iPod headphone volume control controls your IPOD, and will not control the detector). Maybe I can just pull the headphones out of my ears a little bit. I am also thinking perhaps the batteries might last longer with ipod headphones??? I will try to remember to update my review when I get my adaptor.I only gave these 4 stars instead of 5 because 1) they are my first set of metal detecting headphones so I have nothing to compare them to yet, and 2) if I were building my own tough as nails set I could see how to make them more durable. That is not to say they are fragile. They are field worthy for sure, just would want to REALLY mistreat them. Otherwise:They look great, they work beautifully, they are comfortable, and the price was right! USA made also, so I'm guessing the wiring is heavier guage and the circuitry is better (though i haven't seen inside it). One of the biggest liabilities of the Chinese crap is the scrawny wires and substandard guts you cant see at a glance. These 'feel' like to they have substantial internals.very happy so far with these headphones!These look the business. They are on the heavy side, but feel sturdy as well. I have not used them for very long, so time will tell. There is a volume control for each ear, which I need with my metal detector because it has no volume control of its own.The main problem with these is that the provided coiled cord (which seems like the right idea for a metal detector) is very stiff. I am getting an effective length of only about 27" or 28"! When I swing the detector, it wants to pull the headphones off on my head. The coiled cord is made of some cheap vinyl, not a nice bouncy rubberized material like my old Koss headphones. Seems like a cheap materials knock-off of something that used to work well -- and that's probably exactly what it is.I am going to hang a weight from my cord which will probably permanently stretch it out; this will get the job done. Now I know that what I really need is a non-coiled cord of about 42".My husband uses it with his metal detector. Loves it.Arrived in the time stated the quality looked good but I have used it twice and now the volume has stopped working so I can't use it had to buy a set from another company.Good product for the price.Loved them.These are good well made and comfy.BRILLIANT HEADPHONES, BOUGHT FOR A MATE AND HE THINKS THEY ARE FAB A+
