I have a pair of Gray Ghost headphones and I could barely hear underwater... I had the same issue with the Gray Ghost on my Excal and I took out the resister (I think thats what its called) and the volume did increase and at least made it audible under water... can the same thing be done to the Gray Ghost for the CTX or is that resister needed? Or is there any other headphones that are available that are louder for purchase or filmware to make the CTX louder?
