Geekria 6.35mm (1/4") Male to 3.5mm (1/8") Female Jack Stereo Headphones Plug, Aluminum Alloy, Gold Plated Adapter

works like it should

Non gli trovo un difetto, addirittura eccessivo l'astuccio in simil pelle.

Werkt goed! Sluit goed aan merk geen vervuiling!

This adapter is designed for balanced stereo signals, however, it works just as well for connecting headsets and earphones with the TRRS combi (combined headphone and microphone) jack if you don't want to use a traditional TRRS splitter and have the microphone end flapping around doing nothing. I've spent too long getting frustrated looking for an adapter that works correctly with combi TRRS jacks. Then I found this one. The other adapters seem to have lousy placing for the ground contact meaning it struggles to make a good connection with TRRS jacks, and you have to have the 3.5mm jack hanging out slightly which gives you a poor mechanical connection meaning your 3.5mm jack could potentially just fall out, or become misaligned again ruining the audio quality. Because this is expecting a 4 pole (TRRS) jack for the balanced signal, it has correctly positioned contacts allowing solid connection both electrically and mechanically. I think the seller should consider marketing this little adapter as being useful in this secondary usage. I would've probably found it quicker. The adapter is about the same size as most of my other 3.5mm to 1/4 inch jack adapters and has an all-metal construction, featuring gold-plated contacts. Jack insertion is a little tough but it's the same force required as pretty much all my other adapters. I just wish there was a Right angle version for compactness.

V good build quality
