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

Hi Sergiy welcome aboard..A few questions for you:
Do you want plug in cable OR will you get something wireless & use the excellent Bluetooth?
Will these be used strictly at home or do you need something that you can take with you everywhere?
 Have you heard any decent headphones & what was your experience listening?
 All that said I have demo'd pretty much everything under $1000.00 U.S. including:Audeze LCD2 & LCD2 Fazor,HiFiMan HE560/Ananda/HE1000 & Sundara,several Grado's,several Sennheisers & Focal all the way to the top..Of all I have listened to my absolute favorites were Sennheiser HD800S & HiFiMan HE1000 but couldn't afford to keep the Sennheisers so settled for the HiFiMan Sundara($350.00 U.S.$),which IMO is ABSOLUTELY BEST open back headphone UNDER $1000.00!
For BlueTooth the HiFiMan "Deva"would get my $..
Check out:head-fi.org & spend time there,amazing place for headphone lovers...Good luck...
My wife ships to family in Russia a lot, or did, the last year or so has been rough. Not only Russia, problems shipping to UK as well. I will spare you our horror stories. So first question before even talking headphones, who can ship what and will it get there? You might have better luck buying new for this reason alone.  
If you buy from Ebay they have a Global Shipping program using USPS that I have used to ship to several EU countries with flawless results..
