It works, but check and see if your headphones make a snug connection.
I check to see if the issue was the apple headphones, but they work perfectly fine on my iphone.
Just the right amount of reach.
Great piece of gear.
If I lightly hold my headphones Jack in the extension it sounds fine, but if you try to plug it in it sounds muffled like you're under water.
I'm on my second extension cord.
I have to keep it halfway unplugged or the volume drops substantially.
I do not recommend this cord.
The feed is terrible, If you plug your headphones all the way in, you can't hear it on both headphones.
