In my opinion you can't beat the headphones from DetectorPro. My two favorites are the DetectorPro Black Widows and Gray Ghost NDT Headphones.
The Jolly Rodgers Ultimates are nice headphones too... they are a lighter then the Black Widows and Gray Ghost, making them nice in hot weather, but I just like the heavier studier feel of the Gray Ghost and Black Widows.
The Original Gray Ghost Headphone are nice, if you don't mind not having the separate volume controls.
The Black Widows, Gray Ghost NDT and Jolly Rodger Ultimates all have separate/independent volume controls which I really like. All people hear better in one ear then the other... as you get older, it become more pronounced. So even if you don't really need separate volume controls now, you most likely will later in life. Just something to think about before buying... and all DetectorPro Headphone have a life time warranty.
The Garrett Headphones much less money, but just don't hold up well, I had a pair as a second set and they just died... and they're only two years old... and I didn't even use them much! My daughter also has a pair and with her pair, the ear pads started falling apart after two years of use. Don't know what's up with that, or if anyone else is have the same troubles those phones, but that's been my experience with them.
Killer Bees also make a good headphone... I just like detectorpro.
Best wishes with whatever headphones you decide to go with.
