Pros: Engaging, open and clear sound
Cons: Looks cheap, bright and fatiging
Actually I bought this headphones just for it's box. I own the one and only HF1 prototype and they come without one.
Anyways, they‘re of great value,for the price you'll get clear sound and tons of details when paired wit bowls (although not in good quality compared to more pricey models). They are outstanding rock headphones, especially in it's price range.
But like most Grados, they are quite bright and can be fatiguing.
