Hi Art, 

Its hard to beat the Bose Quiet Comfort QC25 -- or the older QC15 -- 
in a noisy environment. 

There's a terrific sale on new Quiet Comfort QC25s right now for only $115 


For an additional $70 you can add an Antlion ModMic 5 modular attachable boom microphone

I use the CM500, and have for a couple of years. 

My shack is next to the laundry room, and I do hear that sometimes. My wife 
tries to avoid doing laundry during some contests, but sometimes that is 
unavoidable, as there are lots of contests. No it isn't the greatest at 
blocking out external sound, but I'm not complaining for $60. I don't 
usually have problems with external noise, yes I hear it, but it isn't 
usually bothersome. My biggest problems have come during Field Day when 
people are standing around talking around you, not from things that tend to 
have a constant hum or the like. However if you're that close to your 
furnace and it is that loud, they still may not be a good option for you. 

I've also used Radiosport RS60s. Yes they work much better at blocking 
external sound, but I can still hear people talking (just not nearly as 
much), so they aren't perfect. I do like them, as they are reasonably 
comfortable, but the weight gets to you after a while, or at least it does 
get to me due to some neck issues.
