Adapter USB Type-C to 3.5 mm

Arrived faulty. I tested the item on three different phones with no luck. The first two were android, so I thought it might just be an only Iphone compatible. Then I gave it to another person that uses Iphone as a present due to the fact that I couldnt use it with Android. The person got back to me the following day saying it was not working on their Iphone either. Unfortunately, I was unable to return it for refund as I am now back from holidays and in another country.

It works, but I swear the sound is much lower with this adapter than without - for example using my headphones with my computer where I can plug the audio cord directly. I'm considering looking for another option.
