Geekria 4.4mm to 3.5mm Balanced Headphones Adapter Converter for 3.5mm 4-Pole Cable to 4.4mm Player Device, Durable Aluminum Alloy Conversion Audio Plug, Gold Plated

Works as expected

Fa il suo mestiere: non ti fa perdere tempo a ricablare le cuffie quando devi andare in sbilanciato. Bisogna fare solo un po' attenzione perché vuole il suo spazio.

Had an old ZTE earphone of exceptional sound quality with 2.5mm male pin. Now I can connect it to any present day female audio jack of 3.5mm and enjoy the sound once more

This is, so far, the best 4.4mm to 3.5mm conversion gadget I own. I have extensively used a few other 4.4-3.5 conversion wire, but this specific solid adapter delivers the best sound quality. Perhaps it's due to the lack of wire media that caused certain signal communication degradation. Highly recommended!

Perfekt.

I bought this to use with the FIIO KA2 and would recommend it. I haven't encountered any issues with it. However, I noticed that one of my IEMs (KZ ZEX) is producing some kind of distortion. I suspect it's because of the cable from my IEM, as I don't have the same issues when using other IEMs (Salnote Zero and Shure SE215) or headphones (such as ATH-M50, Sony XM4, Steelseries Nova 7, Surface Headphone 2). So, if you experience any distortion, it could be due to your cable. One workaround is to use an AUX extension. I have a 10cm AUX extension that I use, and it eliminates the distortion for the IEM that I had issues with. However, what worked for me might be a different case for you, just keep that in mind.
