Monoprice 107126 3.5mm Stereo Plug to 2.5mm Stereo Jack Adaptor, Gold Plated

There is a lot of feedback here about things working and not working. So, let me be specific. I wanted to use my existing headset -- an older Etymotic ety.com that terminates in a 3-conductor 2.5mm plug -- with my new phone -- an Asus ZenFone 2E, which has a 3.5mm audio jack. This adapter works perfectly for this purpose. There are no problems with fit or audio function, either mic or earphone. This runs counter to the product description, first bullet ("... it will not support the speaker or mic functions on the headset"). What can I say? I took a chance on the thing, and I got lucky... I guess.

Great. Simple. Exactly what the product says it is. Works just like I needed for using a older flashing triggering cable with a PocketWizard unit (yes, I am not even using it for audio) and saved me some money over buying a new cable for the purpose.

The internals of the product broke apart and became completely loose pretty much the moment I jacked in a plug for the first time into the female end of the converter, shortening its lifespan of function from whatever it's supposed to be to about.... 2-3 minutes? Absolute junk.

This item is to make a small 2.5mm jack adapt to a larger female 3.5mm jack, not the other way around as one may read the title. Thus I was unable to use the product.

Does the job, has survived countless dozen connection at both the male and female connectors. female end is a little tight for my tastes but I haven't wrecked a cable yet so it's fine.

I gave this product a 4 stars because it "worked", however the large black plastic outer shield or barrel was just a little too fat to fit into the headphone opening (not the jack itself), so it required a bit of trimming with a single edge blade. Now up close it looks a little hokey, but at least now it allows the jack go in far enough to make contact with the inner (female) portion. I just hope that with the missing bit of plastic, it holds together. But I am happy to have purchased it and it makes a world of difference.

Adapter is exactly what I expected. Fits perfectly between my Plantronics (2.5mm) headset and my Samsung Galaxy S6 Edge (3.5mm) phone. I use the Plantronics corded headset when I don't want to use a Bluetooth headset.

Got a microphone/headset from work, but it was too small for my iPhone jack, so, I found this and it now works like a charm. 10/10, would buy again.

Parfait!

Does everything as advertised no more, no less. All I can ask :)

as described

When I plug 2.5mm headset into it, the plug wobbles around. I have had to tape it in place with electrical tape to make it work. And it took over a month to travel via sloth mail from the US to Canada

Garbage! Won't work properly unless you wiggle the cable to no end. Scratchy sound on audio, non-stop errors on data connections (temperature probe, etc). Would never buy again!
