Hi All, I had to buy new headphones for my GPX 5000, So I bought Sportz Titanium headphones with a mic. from After Shokz. They give a very strong signal on a target, on a big target they don't blast the sound into you ears because the phones sit infront of your ears against the top of the cheek bones, that is fantastic. First I tried it with a 15" Evo but the EMI was very strong, nearly unusable, then I tried it with a 12" Evo that was much better but still the EMI was very annoying and I was scared of not hearing the very faint signals. Has anybody had experience with Bone COnduction headphones from a different manufacturer?
