Here you will find my custom built waterproof metal detecting headphones called the Hydra-HPs. I have several models now depending on your preference and use. There is the M1’s, M2’s and M3’s. Each are unique and to their design.

The M1’s are the most common and use the Audiosears receivers for some of the best audio response possible. These particular speakers are waterproofed in a custom made housing and is made to handle wet conditions like hunting in the rain or in deep water. They can get wet and dunked underwater but they are not meant for diving purposes. For that you would want the M2’s.
The M2’s are the same but they waterproofed in the front differently in order to withstand the water pressure of diving. As a result, the sound levels are slightly lower but still very acceptable for use with your detector.
The M3’s are different as well. They use a piezo driver instead and sound a bit different. They are diving capable but not bright sounding as the other two. These are more recommended for the Excalibur user who likes to hunt in pinpoint/all metal mode. Not as common but some users like these for their response in all metal and can help give a little more distinction to the sounds.
For the connector type, it will all depend on what you are using.
For the Excalibur, it can come in a couple different ways. But the main thing is, you have to wire it through an end cap. So if you need an end cap, that will be an extra charge and additional fee if you want a connector with it instead of it directly wired through the end cap with out a connector on it.
Over the years I have made some posts on the various headsets made here so if you want see more, feel free to check out these prior posts as well:
