I did not have the budget to buy studio monitors so I thought to invest in some good headphones. After reading thousands of review, I chose this one at 250 Ohms.
Beyerdynamic is a long story brand, reliable and solid.
The sound quality is impressive and does not affect your ears after listening for hours.
They are very comfortable to wear for hours and hours, totally different from my Marshall or Beats. Since they're overhear studio headphones, they won't let you get tired. Moreover, the soft material inside the headphones make them soft and comfy as a pillow.
They are well-built and the material used is solid. I have them since December and I am satisfied.
I do not see any cons to these headphones and I really advise you to buy because they changed my musical perspective.
I recommend you to choose the correct amount of Ohms.
I will definitely buy a new pair for mastering.
