9-inch 3.5mm Mono Plug to Dual 3.5mm Mono Jack Splitter by Infrared Resources

I have a very specific need for this splitter and to that end it works perfectly. I have a small AM/FM transistor radio that I like to take to MLB games so I can listen to broadcast while watching the game. Before getting this splitter, I had to take turns sharing the radio with my wife or blast the speaker which annoyed people sitting around me. Now, we can both listen to the broadcast simultaneously each with our own earbuds and I am glad I don't have to take turns or annoy anyone :) As for sound quality, who knows? It's monotone AM radio and I'm happy I found an inexpensive solution that works great for me!!

Exactly what we needed, delivered on time and works fine.

Bought this to split the mod wheel jack on a Korg iMS-20 controller so that I could send it to two destinations simultaneously. Works just fine.

Perfect for splitting the signal out of my IR blaster. I needed their 2.5-3.5mm adaptor as well but am now getting direct connection to all of my component

They connect well. Used to splt ext speaker from VHF radio to external in cab and PA speaker for work truck

The back of some model Samsung tvs... have an IR output. This way you can use the tv's ir receiver to transmit to a blaster in a cabinet somewhere else. This allows you to split that signal. Works great.

Works great to expand IR control. No problem driving 2 emitters with HUB

Inneffective as trigger on/off connectors.
