Would say that probably standard Beyer so if 770 firts you T5p would fit as well.
I dont know about highs as I am not much trebel sensitive or I haven’t yet bought some treble murder headphones except for M50x 
I also dont find them having very spacious soundstage comparing to other HP I have.
Also what music you are listen to and what is you budget. Others might be more insightfull as I am still rather noobie but this also can narrow recomendations.
