I have tried several different headphones with my MP and have the same
prob on all sets.  Some report the same on FT1000.

Increasing the trimmer pots increased the audio hiss but nothing
significant in terms of volume.

GW4BLE sent me a copy of an official Yaesu mod to increase headphone
audio.  This was specifically for the Heil headphone but I dont think
the problem is headphone specific!

Call Yaesu USA for the mod
