The laptop does not recognize it; it sees it as an unsupported device. New laptop with Windows 11.

The microphone on the CUBOT P30 phone works when it remembers, and it doesn't charge at all. On the SAMSUNG tablet, it displays a message to check the connection, even though it shows that it's charging.
When I contacted the store where I bought it, they told me that my phone is probably not compatible. Don't buy it because it's a waste of money, there's no reason to (for the few euros it costs).

It never worked on iPad Pro 2018, the type-C was difficult to insert into the iPad's port and if you removed it and plugged in the iPad's cable, it wouldn't charge?!?! The iPad was new at the time and had no issues with any other cables. I don't have another device to test it on. It was returned to the store.

Often it doesn't even work, and when it does, the sound is completely distorted and awful. If it doesn't work, then it's like throwing away the money, no matter how little it is.

The price is very good but it doesn't work for the job you want. The charging of the phone is very slow and the sound is not always audible from both headphones. At the same time, it creates a problem during video playback as it often stops and adjusts the volume...

Compatible with Samsung S5e Tablet. Charges normally and you can hear sound from the other port with headphones simultaneously without any problem (I'm not sure if it is compatible for fast charge, I will check and update the review).

If you want to replace the charger with a USB stick, forget about it. It is only for charging, not for having a USB stick and headphones together.
