HiBy Impedance Adapter

Poor fit

Great build quality and a convenient size/form factor compared to other solutions like IEMatch, but bafflingly the entire 2.5mm jack assembly is very slightly larger than it should be, meaning it can barely hold onto any cable you plug into it and has enough wiggle room to constantly make the audio cut out.

No Problem!

New Lotoo Paw S1 pumping out too much power? Refuse to go back to that flimsy 3.5mm single ended connection? Welp, this product may help. This impedance adapter does help on sensitive IEMs from the 4.4mm balanced jack and doesn’t otherwise alter the sound. Solid construction, strong (yet flexible) cable, and plays well with the balanced jacks I’ve used on the Paw S1 and FiiO Q5S. Limited use case, but excellently done.
