USB noise filter, jitterbug or ifi


Wondering if anyone has felt this improved sound from USB memory stick of flac files to dac( in my case oppo 205)

They claim reduction of jitter, rfi, emi, packet errors. Active Noise Cancellation Technology , ANCT, uh oh looks patented!

Snake oil or legit?
Anyone know how it works
Only $50

(1) Erik provided you wise advice.

(2) FWIW without prejudice to his comments in (1) above, I bought the AUDIOQUEST DRAGONFLY USB DAC to bypass the crap POS sound card in my laptop. Prior to buying it it, demoed both the AQ DRAGONFLY “Black” and “Red” models with the the AQ JITTERBUG .

MY TAKEAWAY:
(A) I found miniscule ( if any )  to nil improvement in audio reproduction with inserting the AQ JITTERBUG with either model of DRAGONFLY USB DAC.
(B) = I passed on the JITTERBUG.
