After almost two weeks of testing it, I did notice an improvement in sound quality; I tested it with about $7 KZ EDX.
Regarding the microphone, it didn't work on a Google Pixel with Android 10, but it did work on a LG G6 with Android 7.
I didn't look very well at battery use, but I do have to say that phones are downloaded a little faster; so I consider them just as illustrative for those who want to have a rough idea of the energy consumption of the dongle.
Finally, a slight background noise is heard when no audio is played, which may be a little annoying.
I thank the TeknoGeek YouTube channel, whose review encouraged me to buy this item.
Thank You!
I recommend, you have an improvement in quality than if noted.
I broke into Xiaomi-a headphone jack.
I decided to try this device, and I just took it off!
Chic and loud sound!
The fact is that I have an adapter usual for headphones for the socket from charging. but then the sound is quiet and about nothing. and then just-lie down the song)
Perhaps he also plays well in conjunction with the program-not long ago I bought a paid version in the play market.
Approved and compatible with Samsung Note 10 plus
Works well, no noise or bad signal.
Works great with Motorola one vision, sounds better and louder than the built-in DAC.
I personally think the product is a bit disappointing not very bad but also not very well, My other DAC that came in a day later sounds much better but it was also slightly more expensive.
For the price it is reasonable but I recommend to spend a little more and buy a better one.
Work like a charm on my galaxy m51 who already has a 3.5 mm audio
Good quality audio better than my internal dac
Same volume
Clearer sound with sensitive iem no hiss or noise
