Light weight headphones

Out of the dozen I own the best to have on your head is the AKG 240 .
Light with good sound , not much money, and they still sell well 
after 30 years

On my head right now .

I have both the Audeze LCD-XC and Stax 009s. Both are heavy, which is the main reason for my short listening sessions. If I could find phones that sounded as good but were lighter, I'd be interested. I have owned lighter headphones but I'm just not comfortable with the tradeoff in sound quality.

Sennheiser HD600.  if you listen to classic music. Very lite , neutral, and comfortable. Pair with tube amp and it sounds heavenly.
