They sync very well and I like the magnetic open / close on the case. This is part "C". Very satisfied with my purchases from Avidlove so far. I bought these pads to replace my factory pads that came with my ATH-40X. But then I get silence and no cable shipment. Every aspect is mostly balanced and I find no distortion even when at max volume. This wine rack is exactly as describe. lolAs for the item itself, it seems fine and fits the typical AmazonBasics theme of being a basic item that functions well, isnt fancy, and is reasonably priced. The material is very soft and comfortable against the skin. Its REALLY irritating.
