Making waterproof headphones - advice

[dmnz]

Tech Question!



I picked up an Equinox 800 to test and it seems pretty decent.

Wanting to try it in the water, and have some spare XCal waterproof headphones.

I can make the right plug to fit, uses a 3.5 stereo jack. I am assuming the equinox is setup to drive standard headphones.



To drive the piezoelectric speakers in the xcal phones, do you think we would need to add a 1k / 8ohm transformer into the cable line?

Direct there is basically no volume, if I wire direct and place a 100ohm resistor in parallel, I can get some volume, but very limited.

Or any other thoughts how to drive the xcal phones from a standard audio source?

If they are like the CTX....there are 3 pins used...not two. A wire on each pin...BUT you have to jump two of the pins with solder to get full volume... the other isnt. To be waterproof you must have the 1/3 stereo connector true....but it has to be threaded and match the O rings or water will go in thru the headphone jack.

Not like the CTX (I made my own waterproof phones for that one) .

I have made the waterproof connector for the NOX / just sorting the headphone wiring....
