HodgeEnterprises.com review: kotion each pro gaming headset g4000 1

I bought this Gaming Headset as well as 2 more Redragon headsets from wish. All 3 sets have Way Too Small ear cups. Cannot get my 2-1/2" tall ears in them at all; let alone using them for any length of time.
Were these for small children? Redragon S101-1Bass HD Gaming Headset is another of the 3 purchased. Not a one can be worn by me.
The Ear cups are way too small!
Sadly, the Gaming keyboard I bought is losing the black covering from the A and D kees used a great deal for movements in ARMA 3. The coating is good looking; just Not stying on the keys. Model 101-1 Keyboard and mouse set. Make the key covers of a Black material with a Clear or translucent letter or number perhaps. It should be easy enough to do so.
Who do I return these too? And how? Or do I just sell them on Ebay eith a Ruler beside them to show the inner cup size shown.
