Forgive me if this question has been thoroughly covered before - my search results were not much help. Anyway, I am new to the Garrett series of detectors - primarily use Minelab. I recently purchased an ATX, it arrived about a month ago when I was deployed and I am finally getting a chance to play with it. First and foremost, what was Garrett thinking when they designed a proprietary headphone connector - particularly since the stock headphones appear cheap and are incredibly uncomfortable. I thought that the Koss headphones that came with the CTX3030 were sub-par. Nevertheless, I purchased a standard headphone adapter cable from Garrett in hopes that it would solve my problem - allowing me to use aftermarket headphones. Now ---- the problem is that the external speaker won't turn off when the aftermarket headphones are plugged into the Garrett adapter. I am at a loss.....What aftermarket headphone configurations are you guys/gals using with your ATX? Thanks......
