My favourite ones are the Gog headphones made by Gordon Heritage in the UK (made by metal detectorist for metal detectorist). I got mine from Detectorbits but not sure they still have them. I think Gordon only make so many a year. (Goggle them) They cost me around NZ$200 at my door. They have a volume control as well. Very comfortable and you can hear a worm fart. You can wear them all day no trouble. Rainproof but not for wearing underwater.
For underwater I use Detectorpro Grey Ghost Under Water Headphones. But mine have a special fitting to
fit my Minelab CTX3030. Good phones.
On my Excalibur I just use the stock standard underwater phone as they are directly wired to the machine.
They work fine.
Just remember though that some people get carried away with headphones, thinking they make the difference between finding and not finding. This is not generally the case.
Gary Drayton in Miami told me if you really want the Rolls Royce got to “Black Widow” also made by Detectorpro. - “Once you go black, you don’t go back” Do not get them wet. Gary uses them on his deep Spanish hunts. Hey if anyone in member have got a set I would love some feedback
Kate, I’m sure there are a lot of other good ones of there so do some research. Look at other overseas forums - plenty of info out there.
Hope this may help and good luck.
