I've been using the original headphones on the F70 since I got it...all busted up and held together with duct tape..the male plug has worn itself to the point of sporadic in-operation. The leather ear cuffs are rotten, so...I bought a HOSA css 105rr tsa stereo cable for 2.69 off the internet and it showed up today...its two right angle 1/4" stereo plugs connected by 5' of cable..shipping was 3 bucks, so that came to 5 something..then I got a shrink tube assortment kit from the local hardware store for another 3 dollars, I also stopped and got a Fosters 24oz, 1.89 plus deposit... I took the headphones I got with the ATPro, cut off that plug and soldered one right angle plug on, giving me enough cable to stand up when the detector is on the ground...they work great! maybe I'll take a set of Pachmeyer pistol grips and replace the foam grip on the shaft? Maybe drop some led ground effect lighting on the coil too? Really trick this thing out?
