[Aathi_15]

Today I bought USB type c to 3.5 mm audio jack ee-uc10juwegin

1)What is the difference between 

Samsung ee-uc10juwegus Rs 3300 vs ee-uc10juwegin Rs 699 

2) Does S21 5g got Inbuilt DAC or not 

3) Does ee-uc10juwegin got Inbuilt DAC or not 

I got S21 5G , S2 , Lenovo k6 and k9 

Sony headset works well with all three mobile phone except S21 with ee-uc10juwegin adaptor, Noticed bass not good stereo works like mono 

Eg : Spotify play like FM Radio
