So i bought the ath pro 700 mk2 only because my friend had a set and i tried them, they are my first really good quality headphones i have ever owned, and so far loving them . The headphones have very good bass but need to be amp to get the full experience a good amp will run for about ninety nine dollars us currency, i will soon be buying a class a b i believe for that price and will use them on my pros. As far as comfort goes i did have to adjust the headphones allot the first two weeks to get them just right for my head and comfort i desired. The headphones them self are very sturdy and need extra padding for the ears so i cut out a old torn up mic cover out of memory foam like material and put it in the ear pads to increase comfort and i believe it increased the bass. on another note the band is adjustable it is made of aluminum and can be bent to fit you head that's what i had to do and the headphones are really comfy and fit my head now. I have ordered replacement pads that are like velor material and will do a mod and will do a update when i get them. Other wise these headphones are a steal and you should buy them while the price is down and before i forget they are modular so you can take the cable on and off and they collapse to be carried in a small case.
