Audio - Grey Ghost and the CTX

I got my CTX the other day and WOW what an upgrade from the exploder!
But ... shhhh don't tell those guys!

Anyway, I went to plug in my Grey Ghost headphones and noticed after I was using them with my detector, that I was next to some homeless lady and I
was disturbing her sleep. My audio was still on even though my headphones were plugged in. I tried to re plug them thinking that
they had slipped out because of the 90% jack, but they kept making sound. Since I am new to this detector, I tried about 10 mins to figure out how to turn off the sound, before I just gave up and used it the way it was.
I figured I could look it up in the manual later. Well.... that manual is a piece of junk. Talk about confusing.
So I went on-line and noticed a post about Grey Ghost Underwater Headphones and the CTX,
They also mentioned Koss. Normally I dont use the Koss headphones when they come with any new detector, because they are really hollow sounding.
That got me to thinking and I knew I had a reserve pair of headphones in my car that were the standard Koss headpones.
I turned on my machine and plugged them into the CTX, then ran a quarter over it. No outside audio could be heard, but I could hear it in the headphones.
Then I tried the Grey Ghost Headphones. I plugged them in and the audio was in the headphones as well as the outside speaker on the CTX.
I compared the two jacks on the two different headphones and they are literally the exact same length, size, equal no. of bands and identical in every way, except for the 90% turn on the GG headphones. So I guess the moral of the story right now is to either live with Koss phones or try a plug adaptor for the Grey Ghosts (havent tried this yet to see if it works or not). Basically, my Grey Ghost phones don't work with the CTX without external audio on all the time. Bummer

One other thing that Minelab needs to fix ASAP. The screen is not easily visible in the sunlight with Polarized glasses on. It has black areas that show up when looking through a polarized set of sunglasses. Not good for So. California since polarized sunglasses are required most of the year.
 
Some headphones are now made to work properly with the CTX. SunRay I know makes a set for the CTX, Gray Ghost may as well. If you had the WM10 module I believe all headphones will work with it. I use the SunRay ProGold's, that I have had for several years, with my WM10 module with no issues. This topic was worked over pretty good when the CTX came out. Here is a link on how to make a short pigtail that will allow headphones to work to avoid buying a new set or just using the CTX built in speaker.

Yes that is the problem most of us seen when we tried our headphones we were used to on our other detectors we have. I built the patch cord C&RHunter gave you the link for and it works great. I used the L shaped plug so the jacks don't stick out too far and with the small length of cable the cable is out of the way too. Its been a while, but think I used a extension cord for a guitar that has the L shaped mono plug on it and cut the cable so I had around 8 inches of cable and put a stereo jack on it for the headphones to pug into, works great so I can use any of my headphones on my CTX, but use the Uni Probe mostly as I like to have a probe with it to find those deep coins.
 
I find using a stereo socket to mono jack plug converter solves the problem instantly and cheaply

I've got the SunRay Pro Gold, Sony, Koss, and Maxell headphones. I have to use a 3.5 mm to 1/4" adapter (stereo) for all but the SunRay's and all of these headphones work just fine. When the phones are plugged in, the machine is quiet.
 
Sovguy,
I knew I had seen this somewhere before and finally found it again. This should help with your issue of silencing the machine speaker whilst using headphones:
