The replacement is far better than the original
I purchased a replacement charging chase for my IQ Buds Boost because the original just simply stopped working just a little over a 3 months past my warrenty.
I can't see what's different between this replacement case and my original one, but the replacement has no issues with making the connection needed to charge my IQ Buds when putting them in the case and closing it.
My previous case was far more finiky and difficult to have it function as expected. This replacement case fixes the previous issues I've had though.
