Be aware that much of the time, those certificates are as fake as a $3 bill.
Fake High Res certification, fake CE, fake Underwriters Laboratory, TUV, COC rating, etc. After all, anyone can Photoshop these logos onto the box, Photoshop the certificate documents, etc.
Many Chinese products are made in obscure pop-up factories, by companies with convoluted ownership, and often ODM or rebranded logos by or for someone else. It’s basically the Wild West, and nearly impossible for many of these certification bodies to track, trace, or prosecute violators.
Not to mention fake Knowles drivers, etc.
So my advice is to not get wrapped up in the certificates, or the marketing mumbo jumbo, any much of the other fluff.
All that matters (besides service and support) is the resulting end product - whether it’s good or bad, good tuning, Bluetooth that doesn’t constantly disconnect, electronics that don’t overheat or freeze, screens without ghost lines and bad pixels, etc.
