3.5mm Stereo to Mono Adapter, 2 Pack TRS Stereo Male Plug to 1/8" Mono Female Jack

BTW: This little adapter is strong and the connections are tight and seem well made.The ONLY problem was that I MADE A MISTAKE.I was trying to get the stereo signal combined so that my headphones would now be in mono instead of stereo. However, when I plugged this adapter in, only ONE side of the headphones worked.APPARENTLY: I Need to buy a Mono to Stereo adapter instead.Not the sellers fault so I'll eat the mistake.

splits mono for a sound bar in my pop up camper

Female side of these is very loose causing intermittant audio if cable is moved or even touched. Bad quality.

Needed an adapter for my Uniden SDS100 and non-Uniden external speaker. This adapter works correctly and does not short the earphone jack on the radio . Best solution if not using a Uniden powered speaker.

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.

I was looking forward to using this product. One broke after two uses changing it to different headsets. I reached out to the seller and they replaced the item. So far so good.

Tired of whatever you're playing only coming out of one speaker when you have two? This will fix that, if you're using 3.5mm jacks on small electronic instruments and into your passive mixer or computer line-in like I use to get every sound to come through my (audio) monitors. Great for throwing in the cable/adapter drawer for when you might need exactly this too! Ask my overflowing cable/adapter drawer!

works as described
