I received a replacement set of Gray Ghost headphones and sent the defective ones back. The new ones worked well for me tonight and I found a silver boy scout ring in the lake. The Nokta Makro pair are being sent to Georgia for repair/replacement. I will keep one set as a backup and/or a pair for my nephew to use for when he gets his simplex. Thanks for all of the replies. Hopefully, I won't have any more issues for a while. 

Thank you for the responses. There is no external damage that I can see to either pair of headphones. 

Thank you for the response. In regard to the Nokta Makro waterproof Headphones, I never noticed any crackling. They worked fine the last time I was able to use them and then the next time I went to use them, they no longer worked. After that, I hunted on land with Sony wired headphones using the adaptor and they worked great with loud clear audio. I then purchased a pair of Gray Ghosts while I wait to hear back from Nokta Makro about fixing the Nokta headphones and when I went to use those, I'm only getting audio out of one ear. 

I was thinking if there was an issue with the machine, the Sony headphones wouldn't have worked with the adaptor or I would have issues charging the machine. 

Hi Everyone:

I have posted this on another competing forum. I thought I would post it here as well as this forum seems more active. Part of my issue is the poor volume with wired headphone issue I have seen mentioned multiple times but I can live with that and my issues go beyond that.

I have had the Simplex for a little over a month. I have the Nokta Makro wired waterproof headphones and while they worked OK for a while (volume had to be on the highest setting to be of much use in the water) they recently quit working altogether. If I am in a silent room I can just barely and I mean barely hear a peep out of them if I run a coin over the coil at the highest volume setting and I have very good hearing. I just ordered a pair of the Gray Ghosts for the Simplex and I received them tonight and plugged them in and I'm only getting audio out of one side and they too are not all that loud at the highest volume setting.  I plugged a pair of basic Sony wired headphones into the machine using a 1/4" adaptor and the included headphone adaptor cable and they worked great with very loud audio so it isn't all headphones. Also, the machine charges and updates perfectly fine so I wouldn't think something was wrong with the port on the machine. Could I have just gotten two dud pair of headphones? Has anyone used the Nokta waterproof headphones for this machine or the Gray Ghosts and have had similar problems?

Thanks

I too emailed the Georgia service facility (on 8/17) and haven't received a response. I was going to call today when I saw Dilek's response and I emailed her directly. Hoping to hear something soon.
