[TenTec] Noise canceling headphones

[Gary Tuck]

Got a Centaur amp and except for the blower, it works great.  Right 
power out for this QTH and antenna, easy to tune and QSK compatibility 
with my Orion.  The fan is something else.  Bent the intake fins on the 
case to horizontal and that helped some.  Was looking to replace the 
fan and then thought about noise canceling headphones like the Heil 
Quiet Phone.  Does anyone have experience with these or others on fan 
noise when working CW? There are only a few reviews on eHam.

thanks, Gary
