Samsung USB Type-C to 3.5 mm Jack adapter, White, Ee-UC10J

First, for those who ask why normal adapters don't work on some phones like the S20/S21 series, then these phones don't have a chip called DAC (Digital Analog Converter) which is required to convert the digital audio signal to the analog signal required by headphones/speakers to actually produce sound.Standard USB-C has optional analog pins that can be used to output analog signals to regular audio output. But since those Samsung phones dont have a built-in DAC chip, these optional pins can't be used, instead, the actual adapter (Type-C to 3.5mm jack) must have a DAC chip inside it. Technically not all adapters with a DAC chip will work as the phone must also recognize the DAC chip to communicate with it, some adapters will fully work as intended like this one, or even the Apple original Type-C to headphone jack. And some other brands will work also, but some might have some compatibility issues, like for example no microphone support (you can't use it for phone calls) or the headset buttons won't work, so you won't be able to use answer or end the call or adjust the volume from the headset. Some adapters might even have some audio quality issues like cracking and noise.This adapter because it's made by Samsung works perfectly, all features are working also and it support hi-res audio also. The adapter even works on Windows and Mac systems.

Finally got the original. Tried many places.. Had to return all of them as they had issues.. Crackling sound... Static sound.. Nd one of them even failed a couple of times on day one itself...Got this today nd it works great. The sound is clean.. No static no hissing.. Love it..

The product works well with my Samsung s22 ultra. Both, the audio and the microphone works well with this adapter.

It served the purpose for which it was bought, and as such no complaints.

Excellent quality for calling and music. Works perfectly in S21

Item doesnt work with the 5G mobile A55; the moment this is connected, the mobile screen is in auto-play mode with the volume bar going to zero clearly showing, and the mobile is in vibrate mode. On connecting the wired earphones nothing is heard, and even manually increasing the volume has no effect as in next 2-3 seconds the volume bar goes down to zero automatically. Unfortunately could not use it after delivery, and lost the window of refund. Tried the work around from Samsung forum (USB routing check in developer mode of mobile), but does not work. Stuck with it. If anyone knows how to get it to work, will be appreciated.

it is a very good product

FINALLY. I've bought so many of these in the search of one that will work with my Samsung S20FE. Goodness, it's been hard! This seems to work! And audio quality is good. Excited to use my wire earphones again. Definitely recommend.
