Does anyone with an ATMax have feel the audio is not smooth like the ATPro ??headphones ?? My ATPro with Garrett Z Link has a nice and smooth audio and my ATMax has a harsh, crackling audio .......after trying many,many settings... a smooth audio cannot be achieved. I hope Garrett will address this issue, as audio is very important to my success of great finds been in this hobby since 1976 . Hopefully Garrett will respond HH Tony Perkins.
