Review: Works as it should - Picked up one for a test drive. Allows me to have one leash running from my dac to the front of my desk, and I can run 3.5mm into one jack (4.4mm), as I prefer not having to fiddle around to swap headphones and iem's. I was pleased enough to pick up a second for my other system. good positive fit and click into the jack, nice solid build and good weight and it looks nice. zero noticeable difference in sound quality. 10 of 10, actually bought again and would recommend
Review: Good quality and fairly priced - Good quality adapter and works great with my 2-pin IEM cables. Now I can connect them to my 2.5 balanced port on my FIIO K3 desktop amp.
