Below are excerpts from the review:
I have used no name XLR to 4.4mm adapters from Aliexpress before, and almost all of them degraded the sound to some degree. XLR44B does not alter or enhance the sound in any way or form and sounds exactly like the raw XLR output. As a 4.4mm aficionado who hates fat XLR terminations with a passion but appreciates their rigidity and old-school charm, the XLR 4.4B is a lifesaver. Another important thing I would like to mention is the gold plating on the XLR pins of this adapter. I have noticed discoloration and oxidation even in high-end interconnect cables. But even after over six months of use, the XLR pins on my XLR44B look as good as new.
