It only worked when I turned on the mobile, but sometimes it didn't work at all. Usually, it would buzz for a few seconds and then nothing, possibly losing power. The sound it produces is excessively loud (I had it on silent mode and it still made noise). My port is functioning normally, and my headphones don't have any issues with any other device.

Purchased on 04/08/2023 at a price of €5.90. It does its job when there is no sound playing from the mobile, only a buzzing noise can be heard, and surely this should be responsible and not the new Razer headphones (if it was the headphones, they would buzz when I plugged them into the computer or an Android mobile). It doesn't bother me anyway, whenever I put them on, I hear something, and if I don't hear anything and it bothers me, I mute the sound. Apart from that, it works fine and so far it functions properly. I will come back with new information if and when it breaks. For me, it's worth it anyway, but if it breaks, I will consider getting an Apple one.
