Review on External sound card BEHRINGER U-CONTROL UCA222 by Wiktor Barczuk ᠌

I attempted to sync my guitar with my phone's music library. The guitar is notated in standard notation, although there are very few high ones; when high frequencies are added to a guitar rig, etc., there is a certain amount of background noise. In order to hear clearly, noise reduction must be used. When connecting a smartphone to a card and then a card to speakers DEXP 30W via the headphone output, the treble is substantially lowered, whereas the sound quality when connecting the phone to the speakers directly (without a card) is improved.
