Used this to give audio in both ears where the radio was built for one channel. Perfect fit. Locked into place and worked perfectly.

Good fit, solid mechanical connection.

Sometimes you need that odd little item that you never expected. I needed to convert my little headsets to mono, so I could listen to my old TV in my RV which had a mono headphone jack. There you have it. This was exactly what I needed. It was shipped in a timely fashion and it works great.

Worked great! I couldn't even find it on Amazon.

I used it on a Playstation PS4. I got a "Audio Decoder 5.1 Channel AC3 DTS Decoder" to convert from the digital optical from PS4 to separate Center, Front and Rear outputs. I used this device to put the center 1-channel onto both Left and Right 2-channel.

Simple device does exactly as advertised. Solid, molded rubber/vinel. Should last forever.

I had a hard time finding this adapter Especially for this pric.e.
Works and fits great.

using it on speaker jack for my yaesu ft-847 ham radio and then to headphones but doesnt work in jack well for some reason

Perfect! No problems. I ordered 6 and they all worked as they should. I'm Happy!

I have a portable ham radio that produces mono output. When I have stereo headphones plugged in directly, I only get sound in the left ear. When I have the mono-to-stereo adapter plugged into the radio and the headphones plugged into the adapter, I get sound in both ears, which is exactly what I wanted.

Fast shipping, easy ordering, great price, recommended seller
