Review on 🔌 Monoprice 107126 3.5mm Stereo Plug to 2.5mm Stereo Jack Adaptor - Gold Plated: Premium Audio Connectivity Solution by Nicole Brand

I gave this product 4 stars because it 'worked' but the large black plastic outer shield or case was too thick to fit in headphones. Hole (not the jack itself) so it needed some trimming with a single edged blade. Now it looks a little ridiculous up close, but at least it now allows the socket to go far enough to make contact with the inner (female) part. I just hope it holds together with the missing piece of plastic. But I'm glad I bought it and it makes a big difference.
