I honestly DO prefer the HiFi phones even for weak signal CW work.
ME too. I have probably a dozen headphones laying around. Several were made just for communications including a Heil Pro mic headset and the others are ipod headphones of one type or another. I really like my Skullcandy earbuds but I can not use them for long periods of time, they hurt my ears. Plus they shut me off from the world which makes my wife unhappy.
I have 2 favorites. One is the Sennheiser HD238 made for ipods. I have used this headphone for a couple of years. It is very comfortable, and is open air type so I can hear my wife hollering "Dinner Time". Besides that they really sound good. I used the multi-band RX equalizer built into my TS-590s to get them sounding just the way I want.
In April my wife dragged me to a Flea Market. I found a set of Dr. Dre headphones. They were brand new in an original box. These are highly hyped headphones for the Rap music crowd. The price was only $25. Since I had my iphone with me I looked the model up on Amazon, they were about $200. I figured they must be stolen or shoplifted. I asked the fellow selling them if I could try them on my iphone to see how they sounded. Well, I loved them, I offered the guy $20, he said $23 and I walked off with them.
I use them for music but found I really like them for hamradio too. Very comfortable and the hyper red color
makes me really stand out as a ham. My wife says I look 30 years younger when I wear the Dr Dre's, I feel younger too..
My advice, use what sounds great to your ears, if you want good sound and look super cool get the Dr. Dre's...
I think the moral of the story is "measurements be damned", it is a matter of personal preference Right on Bro.
