Lost Earbud Replacement?

Hello,

I've had the  EarFun Air Pro Hybrid ANC Bluetooth Earbuds for some time now. No complaints about the quality, it's some of the best I've ever had from wireless earbuds. The case, on the other hand,  is super fragile, and my earbuds fly out at every bump. I just accepted it and hoped for the best.

Well, the worst finally happened and I lost the right earbud.  I was wondering if there was any way to purchase just the single replacement? I really do love this brand, but I can't really justify the cost to replace both at this time.
