I'm planning on buying a pair of headphones for use with my computer. I have a DAC but no amp and don't plan on purchasing one.
I want them not to be uncomfortable and leak too much sound.
 
I have narrowed my choice to these:
 
Audio-Technica ATH-M50X
Sennheiser Momentum on ear or over ear
 
I listen for the most part to movie scores and sometimes to rock on the radio, no games, no movies.
 
I had a pair of Grados i80 but they were not pleasant to my ears, I don't know if it was the sound signature.
 
I realise the Momentums over ears are the most expensive of the list and I would probably buy them second hand.
 
Thanks for helping.

If your ears are taller than 65mm then get the ATH-M50X
If your ears are 65mm or less, consider the Momentum over ear.
 
Skip the Momentum on-ear - it's really kinda bassy and won't do movie scores justice.
