Choosing and buying headphones


Dear.
My name is Sergiy.I am from Ukraine.
Help me choose full-size headphones for the player  Astell&Kern Kann Alpha up to 1000$.There are two main requirements for headphones: comfort and sound quality.
It is possible to buy headphones for www.audiogon.com and send this item to my friend in USA who will send it to me then? Is it possible?
Possible options:
1. Denon AH-D7200 725$
2. Dan Clark Audio Aeon 2 575$
3. Focal Elear 550$
Or it is better not to risk it and buy new ones from the store.( https://audio46.com/ ,https://www.moon-audio.com/ )
Best Regards

Yesterday I listened to Focal Radiance and Denon AH-D9200 headphones (source astell & kern kann alpha). Both in terms of sound and convenience I liked Denon much more. Now the choice must be made between DAN CLARK AUDIO - AEON 2 ($ 770), Dan Clark Audio Ether C Flow 1.1 ($ 1500), Denon AH-D9200 ($ 1500), DROP + MRSPEAKERS ETHER CX ($ 750) ...

Meze Audio makes good headphones in the sub $1k range that are comfortable to wear.
