Input:
I am blessed to be able to afford any headphone I prefer.  However, I always shop based on price and performance.  I own many headphones (Seinheiser, Grado, Fostex) and the list goes on.

These are my favorite headphones, and honestly have not tested any that are better at any price.  They are clean, neutral phones that allow these 50 year old ears hear sounds I didn't think I would.

I really can't find any problems.  Some people complain about comfort.  The only time I have to travel light, I take Klipsch S4 phones.  Every other time, it's these.
