Basic questions for newbie


I mainly stream Qobuz into pi2aes/Roon to a Schitt Dac/vtl integrated amp. But I listen late at night after wife has gone to bed, keeps her awake. Vtl has a headphone out but is about 10’ from where I sit (Long cable, heavy?). 

I have no experience in headphones. What are options I should pay attention to? Do I just plug headphone in amp? Or run from my surface or iPhone ?  Or ???
Thx

If you like the sound out of the VTL then buying a longer cable seems like a no-brainer?  Most good cables are really lightweight.  You will never get better sound wirelessly.
Thx. Ok so if a longer cable isn’t too big a pain, then now what about headphones? I have no clue about them...
What speakers do you have?  What aspects of sound reproduction are most important to you?  This can help narrow down what type of headphone might work best.

I have never quite understood the language for describing reproduced music but here is my best shot: I listen to a lot of female vocalists, some jazz, a lot of music that is spare, with some space to absorb the feeling. Last night I listened to Cat Stevens 50th of Tea for Tillerman and loved his 70 yr old voice. So toward the warm side, I guess, but where instruments are not all mushed together.
Not sure if that’s any help. Thx...
