3.5mm Stereo to Mono Adapter, 5 Pack Gold Plated 3.5mm 1/8" TRS Stereo Male Plug to 3.5mm 1/8" Mono Female Jack

Connections are not consistent. I got this for the conversion from one to two contacts. So they do work and for the price point I needed them. However, on occasion in my truck the connections may loose contact and thus sound on my GMRS radio system. Not often but I wish the fittings or seals would be tighter.

works as described

I am Single Sided Deaf and needed an adapter that takes both left and right audio signals and combines it into a mono signal. This only takes the left audio signal and not both!
