ASA has refurbished heatsets for $75. These are relatively inexpensive
passive units. I've got two of them. The first I bought for training, and
then later I got another for a passenger. I'm happy with them. The longest
trip I've taken was six hours of flying in one day, and I didn't find them
uncomfortable. At least in Cessna 152 and 172, the noise reduction is quite
adaquate. ANR may be alluring, but passive technology is pretty reliable.

I'm not associated with ASA, but if you want to check their refurbs, try this
