Basically I am getting my brother a pair of decent headphones for his 20th birthday. He listens to exclusively rock/punk. Max budget is 150 dollars. What it is looking like is Audio-Technica ATH-M50m, or Grado SR80i. I was wondering if there were any other suggestions. He won't be using these for mobile use, he will be mounted to his desktop. However he is there for long periods of time so comfort is a huge factor and I heard the Grados are an issue in that regards which is why I am leaning towards the ATH M50 right now.
Appreciate any help
