Right now I use the squishy little orange ear plugs when I run my Ryedale.  When no one else is home, I have a stereo that I crank up and I can hear it good enough through the ear plugs.  Most of the time, someone else is home so if I blast the stereo like that, they don't appreciate it  
 
 I tried using headphones, but the ones I have stink.
Does anyone have experience with headphone use with a Ryedale?  I was thinking of busting the budget and getting some of the Bose noise cancelling headphones.  Has anyone else tried this.  Interested in how it worked out for ya.  I would have to dish out 2 bennies for a set of these and find out that they are no match for the sorter.
