Well, a check would be unusual, I am not aware of any reviewer paid for a review, and I would not see that as a good thing, because it's kind of a conflict of interests, although it is perfectly possible to be paid and still be objective. And it is possible to be not paid and be not objective (which is what most amateurs reviewers do, expressing their personal tastes as universal objective truths).
The only time I was offered money was from Avantree as a thanks for all the help I gave them creating new products (I am their main Beta Tester, and Advisor for new products). I refused because I do not want to get money from this. This is my hobby and my passion, I enjoy it because it is an hobby, if I get money for it, it becomes a job, and I will not enjoy it. I hate jobs
Eventually reviewers get free products (not always, many PR give the Test Unit for a limited time, it depends on the Company, the product, and the Reviewer).
This may be also a source of conflict of interests, and I always thought that it was, but now that I receive free units I can say, at least speaking for myself, that it is possible to be objective anyway. I write what I have to write, positive or negative, no matter if I have got a free unit or not. I have reviewed positively units I had to buy myself, and negatively units received for free.
And I was never asked anything in change of a free unit. Only one Company once wanted to have control over what I would write. I sent them to hell.
Audio Technica sent me their new ATH-SR5BT and a second ATH-WS99BT for free (the first one I bought it from Japan), so that I could test the SR (I was apparently the first in the world to receive it) and I can now do quick A/B of the two WS99BT to say the exact difference between the sound with stock pads or with WS99BT. Which is why I requested them to send me a new WS99BT, as I was going mad quickly changing pads in my unit. And I wanted to see if this (in)famous Burn-In is a myth or not.
I must admit, I was scared that the SR5 would not be good, they have been so kind with me, and I love the WS99BT so much, that having to review the SR5 negatively would have been painful.
Luckily they are among the very best On Ear BT HP on the market
Now, about your request:
Above, Denon AH-GC20, ATHWS99BT with stock pads, Phiaton BT 460, Beats Studio Wireless.
Below, Sennheiser M2AEBT, ATH-WS99BT with HM5 angled leatherette pads, BeoPlay H7, JBL Everest 700.
Here what you wanted:

The one on the right was also modified to have more clamping force (the headband has a metal core and can be bent).
