I bought the adapter for my Huawei phone. I opened and tested the product outside the store. I took measurements and comparisons and found that it charged very slowly (0.5mAh) and, most importantly, the volume in the headphones dropped at least by half (maybe even lower) compared to the genuine Huawei adapter (type-c to mini jack) with the same headphones. If the sound volume didn't drop so much, I would keep it, even if it charged eight times slower. It was returned and I do not recommend it at all.

As for the charging specifically on the Samsung Note 10 with the charger provided, it took around 1 hour to charge with this gadget. It works for fast charging. Regarding the earphones, I didn't try them at all, I immediately threw them away.

It doesn't work with Asus Zenfone Flip 8 - edit: because the Zenfone, like many Samsung phones as I have seen, requires an adapter with DAC...

I remove 1 star.. because if someone wants to have it in the car on a stand, then they should look for a different product of another type and not a similar one.
Its use, for example, if you play games, charge and listen with headphones, is very convenient!

Very good and high quality. It does exactly what it promises, nothing more, nothing less.
Now, regarding some reviews I read, it is not recognized by some mobile phones because of the phones themselves. It is not an issue with the adapter. Of course, if you have a Samsung, it is better to avoid it.
In terms of comfort, due to its unique design compared to other similar products, personally it did not suit me when playing games. However, for other uses, it is better than others that are simply bulky and take up more space.

It simply doesn't work, I don't know why.. when I told the company, they sent me a second one for free, but that one didn't work either.. my phone is Samsung note 10..

Nice design, but unfortunately it is not recognized on the Samsung S20 FE... And if it is not recognized on the phone that only has the type-C port and you need it, then what do you do?
