Fairbuds XL 2025 USB sound poor quality?

Hi,

I just bought Fairbuds XL 2025, today I tested it’s wired sound, and it’s Very poor quality, without bass.

The Bluetooth sound is much better.

Im confused, I supposed wired sound will be better.

I have a phone (Poco X3 Pro) with both 3,5 and usb-c, I tried by usb-c only (I haven’t jack adaptor).

A few questions:

-There is analog sound through usb-c? Is this poor quality analog sound from my phone? (It’s sound through jack is OK) Or my phone is only sending digital data, and the poor quality is in the internal fairbuds DAC?

Thanks
