### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great adapter
  

*by B***N on Reviewed in the United States on March 16, 2024*

I am using this adapter to connect a pair of 1/4" stereo headphones to the 3.5mm stereo audio output from my desk top computer. This set up works great. The adapter is well constructed and feels like it will last years. When I insert the headphones into the adapter you can feel a nice solid click to show the headphones are solidly connected. I have now purchased 2 of these adapters for different computers and headphones. I like them that much. Quality item.
