Well, the denon pads are thicker which would probably change bass and soundstage (as mentioned above).
One thing, the denon pads are angled while the T5p has flat pads and angled drivers. Making it even more angled might change the sound drastically (even the positioning on your ears changes the sound).
I think the main reason you find the denon more comfortable is because they're very loose and don't clamp as much. You could always stretch out the headband of the T5p so it clamps less but I wouldn't necessarily recommend it unless comfort is really an issue. If it's because the headphones rest a bit on your ears (which happens to me with my T5ps) just shorten the extension from the headband to the cups to center the ear better. Honestly, when I center the headphones perfectly, I can go 5 hours easily with no comfort issues but if I don't do it right, either it clamps too much and I have to readjust or the headphones are slightly resting on my ears, making the top of my ears very uncomfortable and I have to readjust that.
