I assume you want headphones for home.
Grado SR225 is a great choice. Excellent reproduction of distorted guitars and fast punchy bass. Sound is also very in-your-face. However, despite its bass punch it lacks some power in deep bass, so uberheavy crushing Funeral Doom doesnt sound as powerfull as it could for example. But great headphone for Thrash and Death Metal, Grado just sound so good with fast guitars.
Sony SA5000 is also very good metalcan. Its very detailed and fast sounding so every little vibrants and tones of electric guitar sound are clear as day. Unlike Grados it is less-in-your-face sounding so its more versatile for genres that make use of wider and deeper soundstage. Bass is very punchy and it has some surprising power in subbass too if you can get a good seal with the cups, but its still not very heavy sounding, SA5000 is bit bright headphone wich concentrates on midrange and treble more. My favourite overall metal headphone so far. But because of its revealing and detailed nature, artifacts in albums with bad production and mixing stand out too.
DT770 isnt good metalcan IMHO. It has tons of deep bass, but its also distracting. Overall midrange is bit recessed so electric guitars dont sound that good. I havent heard Denons, but what I have read I fear they might also suffer of too much bass. But Funeral Doom and such are very convincing!
Ultrasone Proline 750 (or PRO 750 nowadays) is good and versatile metalcan. Sharp and detailed upper midrange and treble and very good and deep reaching bass. upper bass and lower midrange leaves something to be desired of, but I havent found it too distracting for metal yet, as the upper midrange gives more power for guitars. Some find this headphone bit piercing in the treble though.
Decent source and amplifier is recommended for all above.
