ABLET 4.4mm Male to 4-pin XLR Balanced Female Silver Plated headphone Audio Adapter for SONY WM1A, NW-WM1Z, PHA-2A

I use the adaptor to connect my Fiio M11 Pro to my HiFiman HE 1000 v2 when I’m around the house but out of range of my main setup. Sound quality better than using one of the supplied cables with an unbalanced 3.5mm connection directly into the Fiio player. Only possible conclusion is that it’s a very high quality adaptor. Excellent value too.
