put on my earmuff-style headphones,

The empeg will not drive those headphones.

The only headphones you can use plugged directly into the line-outs of the empeg are efficient in-the-ear Walkman-type headphones that require very little power. Even cheap Walkman-type 'phones won't work. If they cost less than $20, they probably won't do the job.
