Large black attachments inside wheel?
This morning, I went to have some after-market wheels put on my A-Spec's current tires and the mechanic discovered something neither of us, nor anyone else at the shop has ever seen -- some large black attachments on and inside the wheel.
We didn't proceed any further because nobody seems to know what those are or if we'd do more harm than good. Anybody have any idea what these are and if there's any danger in not having them on a set of aftermarket wheels?
Any insight is appreciated!

Do any other manufacturers or aftermarket vendors use this technology?
If aftermarket is out then Honda pretty much secured the OEM wheels future as very few would want to spend money for an upgrade on rims which will be potentially noisier than before.

Technically, they make a difference, but if someone removed them without telling you, it's highly unlikely you'd notice.
If you look at interior sound levels measured by Car and Driver of various 2018 Accords from the loudest (Sport trims with the 19" wheels without resonators) to the quietest (EX-L trims with the 17" wheels with resonators), the difference is only 1 dB.
It's a combination of tires, wheels, resonators, wheel well lining material, insulation, glass type/thickness, electronic noise cancellation/enhancement, and other factors that all work together to make a vehicle quieter. Changing one of these variables by itself doesn't make a dramatic difference.
Honda has been using these since 2010 beginning with the Acura RL (Honda Legend).

Lexus uses a noise-reducing wheel, too. The concept is similar, but the execution is different.

These "resonators" can attenuate certain frequencies near the wheel by up to -10 dB (half as loud). However, the difference in the cabin is typically only about -1 dB (almost imperceptible).
