Ah this is one of the interesting thread..
I tried Headphones for a while,Sure that they could give the immense clarity to the music compared to the same costing Stereo set-up.
But Believe me, I cant listen more than say 1 Hour, Feel really lifeless and discomfort.But have seen lot of my friends colleagues keeping Headphones on everything even during the work for them the Music is something which keeps them away from other disturbance but very few listen to music with passion.I have passion only with the personal stereo set-up and max the Headphone fill my journey when am away from my stereo.
We cant blame the recent generation due to the current lifestyle as FM'S Said. But I have received WOW from many Headphone manic's when they listen and look to my stereo-set-up.
Again its about the generation and the reproduction of music been changing. Still i could see people say nothing come close to listening the music via Radio(The radio era should be ended by 90's itself IMHO)
But keep in mind, If you like to see if they really love the music in Headphone, Just disable the next Button on the source,Sure they cannot tolerate. In simple people have adifferent view of music nowadays and might think people who spend on Stereo are fools.
I have faced with one of my friend stated that "You goose you would get a best Headphone for 5000-6000 and 5.1 set-up for 10,000 and why you lavishly spending money for two channel. I dont have answer for him, so Just turned on my Stereo and played Ilayaraja's Music. All his questions got washed away.
Music is passion for some, for some its a "Do not disturb Board" ,For some "Iam one in the crowd etc"
But Headphones would be harming a lot in particular In Ear

compared to stereo.
I would wait with love to reach my home to listen music at my set-up and sure the headphone cannot fill-in my thirst.
